Actually Will I have, or else I wouldn't have said it

Well truth be told, some showed very good car control, but nobody seemed to care - big air was all that mattered and how the car landed was irrelevant. No - thats not true either, bad landings got whoops and laughter. So whether you could control the car or not, you hit the ramp as fast as possible and that was it.
Is that a problem? Not really. If thats what you want to do I'm not stopping you. Go have your fun.
But is it the same hobby? Well thats more tricky really. Would you class mountain biking and the Tour De France as the same thing? After all its all cycling. Or F1 and WRC, since its all cars? On some levels yes, on others no.
Whats this got to do with Silverstone? Well looking on MSUK its not the only 'pay to play' track opening up, so there is clearly a market. But that market is consists more of bashers than racers. Which means tracks are going to develop more to suit that market - big air and long straights, but not so technical. The Bristol one looks far too narrow to race on, but ideally suited for the guy shown playing on it with his Stampede.
It looks like the RC fun park idea may be about to become a big thing, but its despite the fact that means tracks getting built, it may not prove much benefit to racing, except in getting new people into the hobby.
