Apparently someone hasn't seen the countless videos of burnouts gone wrong (old school jumping the grass hill "barely missing supra" one is the best).You are not going to take lives then you are burning rubber, unless you smoke them to death.
And i would say that where are a LOT more things that are legal and are more dangerous.
The regaining of traction can be unpredictable... may want to reconsider your statement.
Lastly sure there are tons of legal things more dangerous, there are also many illegal things that are less dangerous. WTH is your point?
