I've been driving a lot lately with my new job (I live in Oxford and work 3 days a week in London (get the bus) and 2 days in Sutton, Surrey). There are several things which irritate me on the roads, though I generally keep my cool throughout the majority of events. It's just not worth getting het up about - that way leads to accidents!!
My biggest gripe is middle lane driving. I generally drive at the speed limit nowadays. With so many miles on the clock and such high fuel prices, it's better for my bank balance!! Even so, whether I would drive 80 on the motorways or 60 as I did the other day (50 MPG, woo!), I always pull over to the left-hand lane if I'm not imminently overtaking something.
I have always been taught to read the road - the cars' speeds ahead and behind, and it's very rare that I get myself boxed in. Unfortunately, not everyone seems to bother about looking at other cars on the road, so they just drive in the middle lane all the time.
I swear that 90% of the slowdowns on the motorways are caused by this one simple inaction. SO MANY TIMES a day I see a middle lane driver holding up a queue of traffic with absolutely no regard for what effect they're having.
The only thing I detest as much as this is tailgating. It's usually an Audi or a BMW, but probably only because these cars are amongst the most abundant on our roads...
The main thing I've been concentrating on in the past few years is to make sure I keep my head and don't react angrily to these situations. You just have to look further ahead and behind and be prepared to react should anything require it!
With that said, one of the most fun games on the motorway is trapping "undertakers". Those are the gimps who try to skip queues of traffic by bombing down your left then dodging back into the fast lane further ahead. (the main cause of this problem is in fact the middle lane drivers, though!!). You just open up a slightly larger than normal gap ahead of you in the queue, and they can't resist undertaking you - or you see them coming up on your left side from way back - then you speed up just enough to stop them getting in ahead of you, and not so much that they can slot in behind you (ie you drag the car behind up with you).
I once managed to get a pr*ck in a beamer boxed in behind a lorry for about 3 miles doing this! All the cars he'd undertaken made sure he couldn't get out. That was satisfying :)
But yeah, there are a LOT of inconsiderate drivers, a lot of drivers who don't look ahead or behind them, a lot who are just plain retards (particularly in town centres...). I'm far from a perfect driver, but at least I *know* that and I want to be a better driver!
