Yeah, I agree it is the same here. What I mean is that if you ride it without paying and then leave it in one of the designated locations or near one of them and there is no permanent damage to the bike the company (I think) will not count it as stolen, will recharge it and keep using it.
So in that sense stolen are only the ones that are impossible to recover.
You can't be bothered by things like reason and facts if you don't know what these words mean
