Traffic Engineers
Hate everyone. Perhaps this is the problem. If you're a driver you will be well aware of the things they stuff on the roads to piss you off and make your journey as unpleasant as possible.
In Northumberland (land of the massive roundabouts) for instance, the bastards have gone out of their way to build roundabouts that actively deny you any idea of what other traffic may be entering. Your only choice is drop the hammer as soon as a likely looking gap appears and hope like buggery that your acceleration is sufficient to save you if it turns out an HGV has recently entered from the opposite side. Brown trousers all around.
If you're a cyclist, you may justifiably have developed the impression that your local traffic engineers are actively attempting to kill you. Cycle lanes that dump you out on the insode of roundabouts just as the road gets dualled, lanes that disappear when the road narrows, lanes that turn right across dual carriageways, lanes that run alongside the road and then magically dump you back into traffic just as the gradient starts to get hairy, stupid foot wide gaps through kerbed sections that seem designed to chuck you off into bus lanes. Oh yeah, bus lanes, you can ride in bus lanes. Go on, we dare you.
If you're a pedestrian, well, there's an extremely busy junction outside my house with marked pedestrian crossing places where there is never, ever less than one lane of traffic flowing. Further north aong the same road there's a pelican crossing where you get <20 seconds to cross four lanes with an island in the middle. Clearly someone is attempting to cull the slow and the weak.
Seriously, WTF is wrong with these people ? Get them some whalesong CDs and a spliff, for the sake of us all.
