But at least on a track, runway etc you aren't likely to possibly take out a bunch of other people with you

And it don't matter HOW much BMW test their cars - it only takes one minro defect in a tyre thats not rated to run at over 200mph to blow - and no ammount of testing or expirience as a driver can mean you can predict what other people on the road are gonna do

Remember, 200mph equates to 5363meters per 60secs - that means every second you are covering 89 meters Someone pulls out on you, you got no fucking chance have you....
