OK, so whose fault is it when things go wrong?
People seem to be blaming the track, but people go there and drive like that, knowing there will be others driving like that too, of their own free will. It's no different to skiing, ice skating or any other sport where anyone can attend at any level.
So everyone going on about how the 'Ring should have better 'elf and safety - what's the solution? Speed limits? Independant car and bike sessions? Less people on the track at a time? Mandatory race licences? Compulsory supervision?
How much are you willing to pay for these measures? The track certainly can't afford to implement them and laps aren't exactly cheap now.
I say leave this how they are and let Darwin's theory run its course. The 'Ring TF days and the un-restricted Autobahns are some of the last great freedoms in this world and IMHO they should stay exactly as they are
