What if trains all of the roads were conveyor belts, so your car would get places super fast? Disregard the plethora of issues that would arise, lol. Or what if there were really long trains without gaps, and there were convener belts on top of the trains, and then cars on top of that?! LOL. That's like magic!
This is something I think about frequently.
I clearly don't know what to say.
