One) the purpose of hookah smoking is that you ARE stationary and are forced to sit down and relax.
Two) if it works, it might be good - but price restrictions and use restrictions make it as much of a pain as a normal rig.
Three) how can smoking something like this be safe to drive? you're paying more attention to the device than the road - please inform me when your out there driving, I'll stay home.
It looks cool and with no coals, maybe a little safer. But until I see it operating and someone successfully smoke from it, I'd be skeptical.
They look like the same people who make the electric shisha heater : http://www.electricshisha.com.tw/
