But somewhere inside Toyota there's a team of engineers who think hover cars might be a thing, and apparently there's a project underway at one of Toyota's "most advanced' research and development areas. We aren't talking Jetson's flying car, more like a car that merely hovers "a little bit away" from the road. Probably a few inches with the aim to reduce road friction. With no wings or ridiculous speed, this is probably no simple process. No one really knows how long Toyota has been working on the idea, or how far along it is. Basically, don't expect flying Priuses any time soon...
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
