It can be controlled by a pair of joysticks, which I would assume would be somewhat similar in its controlling scheme as that of a remote controlled toy car. The Toyota i-Real electric personal vehicle was recently unveiled to the masses at the 2012 Beijing International Automotive Exhibition, and there was no release date nor more importantly, a price point attached to it as at press time. I guess it is something that might or might not make it to the assembly line in the end, and you ought to have a pretty large house if you were to need to ride around in one of these.
It would have been nice to see Toyota come up with a two-seater for this, but they would then have to make sure only one person is in charge of the controls.
