I've been doing a bit of city driving over the last few days, you see these sorts of idiots on a daily basis. One day their luck will run out, when sadly they hit some innocent motorist coming the other way, or maybe a pedestrian.
Speed limits seem to be more of a problem around these rural parts, I had some woman going nuts behind me on Wednesday because I wouldn't go over 30 mph in a 30mph zone, and a regular spot for the speed camera van.
