And if we shared cars instead of owning them it would also save on gas for everyone

And if we paid someone to drive the car around for us it would be swell

Also if we do that we might as well make the car bigger

You know what’s more efficient on gas than rubber on road? Metal. If we made the wheels metal we would have like zero rolling resistance

That tears up roads though so we should probably pave the roads with metal

That’s kind of expensive, so we should only pave metal directly underneath where our metal wheeled car will drive

If we’re going to do all of that it should be bigger. Multiple cars connected together.

Hey we can get rid of gas entirely? We could run this thing using catenary arms and overhead cables. GENIUS!

But what if I crash, because of running red lights or because I don’t know how to operate a vehicle? I can’t possibly put my life at risk. Let the other guy take the hit.
