Mini SUV's. Monstrosities like the Fiat 500 and Mini tanks, Focus B and C Max, Nissan Juke etc etc. No more practical than a normal car, just massive chunks of metal that make crossing the road, pulling out of car park spaces or junctions and absolute pain in the arse as you can't see past or through the things.
Edit: This is probably a rational dislike as the things are shit.
