First of all without gravity and weight wheels won't get grip on the road, so no matter if it's a bicycle, tricycle, or a regular car - you can't drive it in 0 gravity, it will just jump away from the road.
- IshKebab 9y agoYes but ignoring that, or using magnetic wheels, you still can't steer it.
- contravariant 9y agoIf you have a force pushing it onto the road wouldn't that suffice to make it steerable?
- cryptonector 9y agoYou also need some way to counter the centripetal acceleration. The training wheels do that in the tricycle, and leaning does it in a bicycle, but you need gravity for leaning, so in zero g with magnetic wheels&track you could not steer a bike the normal way, and perhaps not at all, but you could steer a tricycle.
- sliken 9y agoCars emit exhaust, that thrust however small could be used to move the car around. Granted not quickly.
- cx_in_the_chat 9y agoCars require oxygen to operate, there's no oxygen in space.
- zuminator 9y agoNobody said anything about "space." "Zero gravity" (or microgravity, anyway) doesn't imply a vacuum.
- dcow 9y agoThis is not what they mean by zero gravity in the video.
