In my opinion there are probably more unwisely aggressive drivers (many appearing to be from Eastern Europe) in Audis than BMWs these days, but there are still some afro-caribbean idiots with red BMWs playing over-loud rap music and a number of young men from the Indian sub-continent who can use two mobile phones at once while racing each other down the M2 (although some of those are in Lexuses not BMWs).

The yummy mummies with giant Mercedes or BMW 4*4s often drive with signally less competence than other women with far Eastern 4*4s.

Then there are the hairdressers nominally of both genders with Mercedes "sports" cars (usually parked rather than being driven).

Golf GTIs and Mini-Coopers are far less of a problem than they used to be.
