re: #175 JC1

Physics, rather than fear of terrorism, will be the limiting factor.

Flying could be way safer than driving. When driving you’re limited to a few lanes on the ground. Flying opens that up considerably.

There’s a reason for ATC. There’s a reason why if you’re anywhere near a city, somebody has you on radar and is giving you precise instructions. Why you need to be at least 500 feet horizontally from anybody else, and it’s dangerous to have somebody bigger than you above you that’ll catch you in their wake turbulence.

When too many cars are trying to fill the same few lanes, you just everybody go slow.
