Becky did the math earlier.. 600 chicanes, 5 accidents. Less than 1%. In truth, not bad at all, by any standard.
More importantly than anything, in the broadcast you SEE every single one of those accidents (as you would expect, with any well-directed broadcasting event), but while racing a 35 lap race on the public server on endurance day, you're unlikely to see many at all.. an accident a 3rd or more of the track away is something you probably won't see.. you just see the "suchNsuch pitted" 20 times or more over the length of the race. You don't necessarily connect that with "another one bites the dust in the chicane" when you're busy running your own race. It does happen, though, constantly. They've just Shift+S'd before you get there to see it for yourself.
I didn't, personally, have any accidents during the race. I chose to drive as hard as I could WITHIN the limit.. but then, I'm not contending for the top spot in the drivers' championship.. so my decision not to drive ON the limit was a constructive one. As a result, by the end of the race I was a full lap down.. but I finished, and I picked up a few points for the team. Other drivers felt the need to take risks because there is more for them to shoot for.. and that's true racing spirit, and I can take nothing away from them. Some got caught out, and some others sadly got caught up.
All I'm saying is that the broadcast exposes those "tragic" moments, and I think that the impression you get that there was bad driving is an erroneous illusion. Certainly, accident-per-lap compared with STCC2.
I spend a lot more time spectating in STCC2 than I do racing, and so I can state this with some certainty. The standard is far higher in STCC2 than typically on public servers, but not better than the driving in the STCC league.
