Some people just don't realise that you need to be cautious of changes in road surface, hazards, in the wet, etc. Motorcyclists tend to be acutely aware of this, but in a car you feel safer to push limits. To be fair though, even the best race and rally drivers in the world still have accidents, random stuff happens. Learning limits and training instinctive emergency reactions on a skid-pan or mud-flat helps.
Then again, some people just don't have functional brains.
These cars deserve some respect, they are quite capable, but Mid-Rear cars are less forgiving than all other drive configurations except Rear-Engine (hence why some Porsche's have the moniker "widow maker").
