Once the gyro is included in the vehicle's design, you can do lots with it. For one thing, you could tap into it as a power source; if not for propulsion, then at least to run things like powering entertainment or HVAC. You could even use the gyro as an emergency power source to get to a charging station. A gyro could be spun up faster to return to service more quickly than batteries can be recharged.
Keeping track of the gyro (so it doesn't fall over when parked) is no more difficult than keeping track of battery power, or for that matter, fuel level in a regular bike. It'd be no problem to include a stand that could be deployed from inside to prevent fall over.
No, this two-wheeler probably isn't as safe as a car.... but this criticism comes from people who ride regular motorcycles??!!
