Of course it does not get by me that it is possible for the bike to continue running after someone falls off for whatever reason but if going down this route I would further integrate a "kill swith" not unlike on a sea-doo (jet-ski) in order to make the bike die upon falling off. The sea-doo kill switch could also function as a safety (key for ignition) so no-one could just hop on your bike and ride off. Because the wrist band sea-doo kill switch mechanism would function like a "key."
Yes, I have a thought. Killing the engine after you fall off is a lot like locking the barn door after the horse runs away.
You want immediate control of the engine speed in the event of an emergency, like someone turning in front of you. Fumbling for a throttle release can cost you valuable time measured in micro-seconds. A properly installed, spring return to idle throttle takes little to no effort to twist and hold. If a rider's hand gets tired he needs to reevaluate his throttle linkage, not make it so it can be locked in the cruise position. That's asking for trouble and has no place on a motorized bicycle.
