Rain = Traffic

Is it just me or has anyone else out there noticed that rain seems to automatically lead to traffic? I mean is there a sign out there that says: ' Its raining, common lets all drive like maniacs' ?

I live in a relatively busy city in Nigeria where traffic is controlled most of the time, except for days when its raining and then its complete chaos.

I mean where is everyone rushing to?

Surely they must realise that the rain is just water not acid and will not get through the roofs of their cars, nor are they made of salt and will melt?

I don't know what folktales they all must have been told as kids, cos they all seem to have the same incontrollable urge to flee once the rain starts, regardless of if there are in their cars or not.

Sure no one likes to get cold and wet, but people if you are already in your cars when the rain starts, its highly unlikely that you'll get wet, besides a little rain never hurt anyone.
