The Scottish guy on the doc can be a pretty unreasonable w****r as well, his name is magnaton if you feel like looking him up.
I find most motorists in Glasgow to be fairly reasonable, even the cabbies. Something happens around rush hour however that turns them into raving idiots. I absolutely hate commuting between five and seven, especially in the dark, purely because of the muppets who seem to think that it is ok to cut in front of you or pull out at a junction.
Then you get the idiots who are determined to overtake you, despite the fact that your belting along at 25mph and there is f**k all place for them to go anyway. Pedestrians as well seem pretty unaware of how fast a decent cyclist can go at, and will happily wander out onto the street just yards in front of you, then get pissed off if you can't brake fast enough or clip them.
