Sometimes I wonder why traffic jams and go-slows are higher at junctions when its raining. Does the weather in any way affect a driver's sense of discretion?

does the weather affect your ability to think before posting?

Because, when it's raining, traffic wardens are not always there to control the traffic. Everybody will now be driving anyhow as if there is a driving competition, which will now cause holdups at the juctions. Nobody wants to allow the other to pass.

BecAuse, during rain, there's no traffic warden to control traffic, people will now be driving anyhow and not allowing another to pass.
