(1) Getting turned off the M42 by Vosa no explanation given, no idea what roads around this strange brummie neighbourhoods will take my hightop. I could stop and have a look at my trusty map, but some jasper carrot soundalike will start shouting at me for blocking his 4x4, despite me leaving 65feet of space he could get around me if he wasn’t so far up my arse already, he needs a tin opener to extricate himself from my rear… 
(2) Being 12 hours into a shift, and still nearly 3 hours out from home! 
(3) Motorists that hoot you from behind at busy roundabouts because I can’t burn rubber with this clapped out old thing I’m driving. 
(4) Cyclists that want a tow to the next set of traffic lights, and get all upset when you stick your left indicator on. 
(5) No left turn. No right turn. Ahead only. No U turns. … 7.5t ahead. you didn’t see before because there’s a nightclub flyposter on top of it. Aargghhhh!
(6) TMs that broadcast-phone the cab to remind everyone “not to answer your mobiles whilst in motion” 
(7) Any planner who’s shift ends before yours does. Guaranteed to send you on a wild goose chase, and when you find yourself high and dry with hardly any time left, the bugger has already gone home! 
(8) Seeing the sunrise when I was expecting to finish by 3am.
(9) Getting the nodding dog on the M25 near Heathrow, 'cos I’ve caught the morning traffic. 
and… finally for now, (10) anyone who walks upto me and says (usually in a scouse accent) “You can’t park there!” when I’ve just pulled in on 4:28 for a much-needed 45…
