I agree but...
That is not as easy as it sounds. In fact Bill did provide enough
distance in front that no bystanders appeared to be in danger and
Bill almost stopped the bike. How much power, how much traction, how
fast a reaction time equals how much distance? Not an easy call.
My understanding is that EV drag bikes have a mechanical disconnect
attached to the pilot (with that kind of power "pilot" seems more
appropriate than "rider".) Perhaps that should be attached a short
distance behind the bike, instead of to the rider, for exhibition
stunts. Then the power would have been cut after only a few feet of
the launch making it easier to stop in time. Plus, its just a reuse
of an existing safety system and not something new that may interfere
with proper track performance.
One can be sure that Bill is thinking about safety systems again.
Hey, I thought I had my EV buggy handled too, until I found out I
couldn't reach the dash while backing up! (and that safety gap is
being addressed) I'd enjoy hearing Bill's input on the subject
(beyond "me no pilot" That kind of power and no serious harm - he
clearly knows what he is doing.
