Re: [EVDL] Reaction time (was: Bill Dube nominated for DarwinAward.)
Yeah, that sounds fine for street driving, but doing exhibition burnouts
requires the use of the front brake with part throttle. The question is how
to reliably detect when the rear tire has gained too much traction and the
bike is launching. I'm guessing there should be an increase in motor
current, which should be easily detectable with no unreliable moving parts.
Or maybe weight on the seat. During a burnout isn't the driver standing,
but if the bike moves, he's not, but that would come later?
