I just assume everybody is a total brainless idiot and act accordingly. You cant trust anybody to show even a basic level of common sense anymore. Cyclists generally arent too bad but motorcyclists are the only type of individual to undertake and speed up just as they see a car pulling out of a driveway with the drivers view obscured by a hedge. Pedestrians are generally the worst, the people who cross a road on a blind bend or wait until the green man turns red then run across just as ques of roaring traffic come round the corner, the type who flail their arms around as they trot across but the legs dont actually move any faster, then look at the cars as if to say 'ooo, silly me!' and smile at you. Thats why these 'shared streets' simply do not work here and any frequent HJ reader will know i am a massive critic of such a poor idea, you simply cannot give pedestrians the right of way on a road. I know technically nobody has 'right of way' on a shared street but pedestrians just meander about without even slightly moving the neck to see if anythings coming (perhaps they think its a pedestrian walkway?) and as someone who was taught the green cross code and given demonstrations of how to use zebra crossing in 'road safety day' at school i find that baffling.

As for other motorists, typical phone using speeding general lack of common sense fare really.
