Very pedestrian

Right, come on, who decided that those bleedin' zebra crossings have to be right on street corners/junctions? I mean right on the junction. This has been bugging me for years, but this morning I witnessed another near calamity, with cars almost piling into each other as one driver stopped to let a pedestrian cross.

And for fucks sake, roundabouts...wasn't it obvious to those urban planning geniuses that sticking zebra crossings on each junction might just disrupt the traffic flow? Ever tried getting across a roundabout near a school when the kids are on their way to/from school? In Blighty, the flow might just keep flowing, but in this country, forget about it. It doesn't even enter into anyone's head that they shouldn't block the road...and thus render the roundabout, which was surely designed to keep the traffic moving, to be about as flowing as Chelsea's football...
