While all questions are very nice,number 6 is even more nice. I also like the quote,nice post |
2undeee:Well said. |
Intelligence work. |

Pumping your brakes several times may rebuild enough pressure in the braking system for you to stop. This may take a while, so keep trying Then, regardless of whether the car has ABS brakes or not, quickly squeeze the brakes down to the floor to make the most out of all of the pressure you have preserved or built- up, as hydraulic (or air) brakes rarely fail all together. Keep the brakes squeezed to the floor. Shifting into lower gears helps slow you by using your engine to slow the car. If you have an automatic transmission, downshift a gear at a time into low range (generally labeled as “1” on the shifting mechanism). be careful not to downshift too Again, if you can’t go directly into the lowest range, try gradually shifting down Apply the brake slowly and steadily your emergency brake can lock your tire if applied too hard or too fast,especially at high speed. If you feel or hear your tires lock, release a small bit of pressure from the brake application and hold it there. It should be stated that if the tires do squeal slightly, it does not necessarily mean that they are indeed locked-up With a handlebar E-brake, one can initially apply it up to three clicks (to enable a controlled slow-down) and then apply an additional one or two extra clicks (to bring the car to a final halt). Warn other drivers and pedestrians. Turn your hazard lights on, and honk your horn to make others aware that there is a problem. (Be sure to know the location of the hazard light button prior to such a situation.) Open windows to allow air resistance to slow you down as well as enable you to shout to other passengers and drivers. If you have room on either side of you, steer sharply from side-to-side. Turning creates friction, which slows your car naturally. If you do not have brakes, try turning sharply from left to right over and over to slow your car down. Do not do this at high speeds . Turning at high speeds may flip your car and turning too sharply at any speed can spin your car around, so be careful. Use your surroundings to slow the vehicle Ideally, you could use a runaway truck ramp, but as these are not particularly common, you’ll probably have to improvise. Keep in mind, however, that these techniques can be very dangerous – especially at high speeds – and should only be used as last resorts Use terrain to your advantage. Try to seek out inclines that you can go up. If this does not bring your car to a stop, be prepared to do some reverse driving and/ or use the emergency brake at the appropriate time. Applying friction to the rubber on your wheels will slow the car considerably without harming other portions of your vehicle Driving through gravel or dirt (such as you might find right off the side of the road) can slow your vehicle considerably. Be very cautious when using this technique. Sudden terrain changes -- especially if only under the wheels on one side of the car -- can cause the car to flip, and may cause serious injury Approach to a graveled or grassy shoulder must be made progressively, smoothly and gently. Small trees and shrubbery will slow your vehicle when all else fails. Try to put your vehicle through the center of a line of shrubs or saplings, being careful not to pick a tree that is too heavy for your car to go through. Trees with trunks over 4 inches (116 mm) are considered dangerous to occupants of motor vehicles. Large trees can be fatal Hit the back of another car Try to strike a vehicle that is traveling at about the same speed as yours (hitting a slow-moving or parked car will stop you, but the deceleration will be quick and extreme) and attempt to make impact squarely on the back of the vehicle. Glancing blows will likely send both vehicles out of control. Be extremely careful not to hit too hard as your airbag may go off. look for a bushy protrusions or shrubs and run it through the friction will significantly reduce car speed to a halt. if there are no bushes go for grass, especially tall grass run the car through the tall grass and it will come to a halt. finally if there is none the last way is go for sand, sand is so unstable will definitely halt your car, especially wet sand.[Quote] God help us |
Point 3 though |
This is some history. |
That girl in glasses is looking so rich |
Africa has a long way to go |
nice and simple,and that number 5 though,and the point 7 is a bit catchy too |
When you don’t have a constant source of income it is smart to reduce your constant expenditure – of which housing tops the list. The name on the title deed on the duplex or apartment you have rented for the past 8 years is still that of the owner and there is no known real estate rule that converts years of lease into direct ownership except you pay the valued asking price to own the property. If every other person who owns houses today chose to remain at the point of making excuses, would they own their houses now [Quote] Thought provoking nice one. |
This enlightens me,nice one. |
I like the ending,nice post. |
CProf:Opportunity comes but once,I advise you to go. |
This is enlightening |

Peripheral details like this can have the effect of making the scene more believable,I like that part. |
including if you need to move to the backseat to get out of the car as the engine-heavy front part starts tipping deeper first Moreover, Professor Geisbrecht says that by opening the door, you invite a quick sink in place of the floating time available to get out. In his experiments with 30 vehicles, he found that all vehicles float, anywhere between 30 seconds to 2 minutes. [15] You could be using this float time to escape rather than opening the driver's side door and giving the water 5 to 10 seconds to sink the car and drown everyone in the backseat The end of the car that contains the engine will usually sink fastest, often leaving the car at an angle where the heaviest part of the vehicle is lower than the lightest. As such, you may be able to open some doors while the car is still floating Break the window. If you aren't able to open the window, or it only opens halfway, you'll need to break it. You will need to use an object or your foot to break the window. You can also take your headrest off and use the metal inserts to break a window.[18] It may feel counter-intuitive to let water into the car, but the sooner it is open, the sooner you will be able to escape directly through the broken window. If you have no tools or heavy objects to break the window with, use your feet. If you have high heels, these might work when placed at the center of the window. Otherwise, Professor Giesbrecht advises that you aim to kick near the front of the window or along the hinges (see the demonstration in the video below).[19] Be aware that it's very hard to break a window by kicking, so find these breakpoints. Don't even try the windshield; it's made to be unbreakable (safety glass) and even if you did manage to shatter it (unlikely in the time you have), the stickiness of safety glass can make it hard to get through.[20] Side and rear windows are the best options for escape. If you have a heavy object, aim for the center of the window. Escape through the broken window. Take a deep breath, and swim out through the broken window as soon as you've broken it. Water will be gushing into the car at this point, so expect this and use your strength to swim out and up. Professor Giesbrecht's experiments have shown that it is possible to get out through this torrent (contrary to some theories) and that it's better to go now than to wait.[22] Look to children first. Heave them up toward the surface as best you can. If they cannot swim, see if you can give them something that floats to hold onto, with strict instructions not to let go. An adult may need to go with them immediately if there is nothing to hold onto Keep your mouth closed to preserve breath and to prevent water from entering. Swim out through the broken window. If exiting via an open door, place your hand on the door latch. Push off the car and swim to the surface. If you don’t know which way to swim, look for light and swim toward it or follow any bubbles you see as they will be going up. Be aware of your surroundings as you swim and surface; you may have to deal with a strong current or obstacles such as rocks, concrete bridge supports, or even passing boats. If it's ice covered water, you'll need to head for the obvious hole created by the car's impact. Do your best to avoid injuring yourself on obstacles, and use branches, supports, and other items to cling to if you're injured or exhausted. Seek medical attention as soon as possible. The adrenaline in your bloodstream after the escape may make you unable to detect any injuries you may have sustained in the accident. if you are still conscious and composed after the first impact then there is 70% chance of survival Then work on the exit, if you are in crowded car or bus, avoid the main exit,unless you are 90% sure that you can get out before the next person.

The car will not gain speed no matter how long you press the accelerator. The drag force of a completely flat tire is that potent. Almost all highway blowouts and tread separations occur on hot days with the car traveling in a straight line at high speed on an underinflated tire or tires. The repeated flexing of an underinflated tire causes the failure. Check your tire pressures and you won't have to deal with blowouts. In an urgent situation, your goal is to move the steering wheel rapidly but smoothly. Jerking the wheel may cause your tires to lose traction. If rough steering causes the rear tires to lose traction, you might go for a spin. Turning the same amount but doing so smoothly will introduce the tires to the request for cornering force and avoid overwhelming them. I calmly and smoothly turned the wheel just enough to miss 80 pounds of steel-reinforced rubber, paused an instant to allow the tires to regain full grip, and then smoothly turned right to return to my lane. so select Neutral and turn off the ignition. The tires with the deepest tread should be on the rear. Tires produce their best stopping force when pointed straight ahead. Here's the problem, however. Many drivers will pound the brake and steer — to miss a deer, for example. They then release the brake pressure with the wheels still turned. With the request for braking removed, the tires are now free to produce maximum cornering power, so the car darts right and hits a second deer — and a tree. That's why you practice centering the wheel before releasing brake pressure. Be sure to center the wheel before you release the brake. Front-Tire Slide When front tires lose grip, most drivers' natural reaction is the correct reaction: Say "Oh, shoot" (or similar). Remove your foot from the gas pedal. Stay away from the brake pedal. Leave your hands where they are. More steering won't help and might hurt. Wait for the traction to return. Pray that the grip comes back before you get to the trees or concrete barriers. Turning the wheel more or stepping on the brake is like writing checks from an overdrawn account. You're already asking for more grip than the tires can provide.[Quote] See problems before they become emergencies by looking far ahead In tight traffic, look through the windshield of the vehicle ahead, or position your car a few inches to that driver's left to see brake lights ahead of him. Process what you see. When the brake lights of all the cars ahead of you flash, something is happening ahead. Slow down. Pressing the accelerator for an instant will give you time to collect your wits. You'll remember to drive straight down your lane and to stay away from the brake pedal With a rear-tire failure, any turning at high speed will likely result in a spin and a devastating crash.

point 3 can catch most people off guard. |
I saw some points |
if u cant see,dont drive: nice rule and i saw some points here. |
let us tread carefully,health is wealth. |
I see some points |
you just want to read from the beginning to the end. |
This is nice |
Don’t leave the engine idling to warm it up, just drive it (after giving it 30 seconds for the oil pressure to come up and get the oil to fully circulate).[/quote]I gained one or two things. |
this is informative |
This is helpful |
I can't really fault any of these points,nice one. |
