It's not just unreasonable and bloody annoying. It's also illegal...
(From BBC News)
Motorists who are found to be blocking the way for other drivers could be fined up to £2,500.
Police say motorists who sit in the outside lane, blocking other drivers are not just being thoughtless, but they cause accidents.
"Lane hogging", as it is more commonly known, can cause frustration and in some cases road rage.
Pc Kevin Druce said: "It promotes bad feeling.
"People get frustrated. They want to pass you and in view of the fact they can't, they then close in on you and reduce braking distances.
"A lot of people in that situation end up braking harshly to try and scare the person away from the back of their car, and, at 70 or 80mph, that can be very dangerous."
Drivers who are caught flouting lane laws will be issued with fixed penalty fines.
But drivers can also be charged with another offence - inconsiderate driving. For this they could face a fine of £2,500.
The police say when they questioned motorists, lane hogging was one of things that bothered most drivers.
I find it quite telling that some posters who partake in this dangerous practice go on to say that they've been driving for years and never had an accident.
They're clearly oblivious to the carnage left behind them as they go about their dangerous driving...
