Clown was in such a rush that he was weaving in and out of non-existent lanes, dangerously overtaking cars doing the speed limit and driving over white stripes to beat a few drivers on a roundabout only to end up at the back of a queue of cars for much longer than if he had just been patient and not driven like a pillock. Gave everyone else behind a good laugh to see his plan backfire. Hopefully his eventual crash affects noone but himself.
You probably shouldn't work in a hospital if you couldn't stay off white lines.
