I've got both front and rear cameras on my Roadster, so I could document all the times I lose as well.
At the dragstip it's all about just having a low E.T.
If you're bracket racing at the dragstrip then it's all about turning consistent times (not so much how quick you are).
Street racing is different. It's all about being quicker than you appear to be. The two participants, before getting into their cars, negotiate a handicap and a $$$ amount. Example, I might say, "Dude, stop yanking my chain, I can hear your supercharger whining away under your 'supposedly' stock Corvette hood. I want 6 cars." ("cars" = car lengths head start). Sometimes you just run "heads up", meaning neither car gets a head start. Or I might only put up $20 against his $40. Or I might negotiate a shorter run (huge benefit for the Tesla). Sometimes you agree to allow the other person to look under your hood, sometimes you don't. It's all about being faster than you look and being a good liar.
I don't have enough battery range to drive to my nearest dragstrip, do a few passes, and drive home. And I don't own a trailer. So for my Roadster it's only street racing.
Some people just happen to find themselves next to a semi-fast car and (from a roll) decide to floor it for a few seconds and see what happens. I don't consider that "racing" and that's not what I do. What I do is "profile" the drivers (stereotypes are fully in effect), motion them to pull over, talk for a bit, negotiate a race. I'm not as much in the scene anymore since selling my drag car in order to buy the Tesla. The behaviour is so deeply programmed into me that I end up still doing it in the Tesla sometimes, but the car is completely wrong for that type of thing. Everyone knows EXACTLY how fast I am and I have no way to secretly make it faster.
