just getting in a car has the same potential, regardless of how good your driving is, there are several million other people out there who arent always as careful.
the argument over how severe it could/couldn't be is a bit pointless, all thats happened is the info has been watered down.
i've been on forums for years, with different cars, and on several of them when ever someone had an off or an accident and you asked them what tyres they were running 99.9% had mixed tyres on.
you may well be a competant drifter and have good balance in your car, but most of the drivers on here aren't; there is only a small group of track day people on here. who to be honest this info is minimal. but for the joe bloggs out there it puts it in simple terms and makes something that not everyone gets a bit more understandable.
