Traffic, traffic, and more traffic

Does it just appear that the more traffic our towns and cities have... the worse the standard of driving? Drivers appear to be becoming less and less courteous and as for obeying the law... what law? seems to be the general concensus.

From blatently ignoring red traffic lights, to at least doubling the speed limit in 30 mph areas... to completely disregarding the law which bans the use of in hand mobile phones - it all seems to be happening more and more frequently.

Those who disregard these laws do so in the knowledge that they stand a better chance of winning the lottery than getting caught and prosecuted for this law breaking.

Why is this happening? I know what I think!
