Given that I have to drive in Central London every day, I have lost count of the times I have been cut up, mostly from these licenced minicabs, most of these "drivers" probably got someone else to take their tests for them, as it is painfully obvious that there is a distinct lack of road training there!
Bendy buses are a bugger as well, most of them seem to think they own the road they roll on, if you get a particularly stroppy driver that decides that you WILL stay behind them, there is little or nothing you can do except stew quietly!
As for the idiots that try to tear past me to go a bit faster, I console myself with the facts that their efforts to be be bit more macho with their right foot is costing them more fuel, and they will get to the next red light first!
I usually try to remember a line written by the Science Fiction writer, Robert Heinlein;-
"Never underestimate the power of human stupidity".
Roy.
