i've never said it saves more lives, it's saved more broken bones and turn signals.

i know many more people who've broken bones buy crashing in a slow speed sititutian than on the road.

i'm a big advocate of learning how to do rear wheel slides.  trick is once you lock lock the rear don't even think about touching the front.
what happens is the rear is locked and sliding, touch the front and it slows faster than the rear, only thing can happen is rear wants to slide around, one way or the other.  so just hit the rear and control the fishtail, start slow on grass the build up to longer and longer.  finally move to the street. better yet, use someone's dirt bike. you just may fall down a time or two.
