It's a classic mistake, one I've done, one I've learned not to do!
Don't rush turn one on the start, especially from mid pack and on the inside!
You'll have so much speed and since your on the inside, passing all the drivers to your left who are in the correct line to negotiate the corner, it's impossible for you to slow down enough and negotiate the corner, hit the the apex and accelerate quicker then them without causing an "INCIDENT", yea your passing other drivers BuT!
I'm speaking about all tracks but this happened to me at SPA tonight and though I fully understand what happened cause I've been "THAT GUY"! (Wish I knew it was coming, would have stopped and proceeded after the car crossed my front).
I started in third, gotta a great start passing second before second gear then passed first at third gear, even before the little red line!
Set up for the corner and just before apex, BLAMO, once I got turned around and back on track I was next to last.
Just spoke with the party I was referring to and since I didn't stick around so as to save the replay, I was informed that the driver that hit me was knocked off line by another driver thus causing the contact!
Everything I have said above still applies!
