What's the point? Especially with something like a RZR-4, mini-van or a Prius. So you sit in the back seat with a controller and "drive" the car from it. Why not just sit in the front seat? A Prius or RZR isnt going into a war zone to get shot at, transport troops, etc..
I could see something like ROV for disarming a bomb where you dont want people in harm's way, but this seems really wasteful and stupid for a mini-van, Prius, Tahoe, RZR, etc..
If the vehicle is driven remotely, it will draw attention by virtue of the fact there is no one in the driver's seat. Not something that you want when you are trying to be stealthy or conduct military operations unsafe for people to be in.
More dumb shit for the war machine to waste fiat dollars on...
