I think you need the tether and the accelerometer. If you T-bone a car, your body is going to take a hard hit before the tether gets pulled. If you just lay the bike down, the accelerometer probably won't trigger. The tether makes me think my electric vest, and how I always forget to unplug it. Maybe it could be like a keyless remote and sense that your body is more than x-number of mm from the gas tank while the bike is moving.
