... speeds without hilarity ensuing. They already have gravity HELPING them stick to the ground, with giant bright lines and concrete barriers and street lights and signs everywhere reminding them not to be jackasses. And still 30,000 people die this way in the US alone every year. What on earth makes anyone think millions of people will be better trying to do this in mid-air at twice the speed with no barriers, lines, lights or sticky-safe gravity? "But air travel is much safer" - sure, with two highly-trained professionals at the yoke, with miles of horizontal separation and thousands of feet of vertical separation with dozens of highly-trained professionals advising them on how to avoid the next perfectly natural thing that might drop them and their hundred+ passengers out of the sky. There are 600K +/- private pilots in the US. There are 200M +/- licensed drivers. I love bopping around in a Skylane as much as the next person, but do I want even 10x more private pilots / planes in the skies? Heck no!
