I can't believe they tried to push the whole track v's street caveat. What a bunch of nobbers, not only does it not make sense from a design point of view, why would you brush aside the considerable slice of the market who wants to track their car at some point.
It's the kind of thing Today Tonight would try to do.
Also, the thing I find funny, if the wheel had exploded on the street and say, caused a fatality, there would be a huge stink made about it, people would probably end up in gaol, and certainly there would be million dollar compensation claims, but since it happens at the track, meh, no one cares, let the hoons kill themselves they say.
