I call BS on that math immediately.
A lane of freeway can move about 1500-2000 people per hour in single-occupant vehicles. If you're moving 2k people/hour in 4-person cars on a fixed guideway, you need to have about 10 seconds between vehicles. That's about 8 seconds for a car to physically clear the switch, the switch to physically move to an alternative position, and then the trailing car to cross the space needed to come to a complete stop should the switch fail to actually work. If you claim 7× the capacity, you need to do all of that in a little more than a second.
So, yes I have "actually put any thought into it." I've put sufficient thought to recognize standard gadgetbahn claims with standard gadgetbahn levels of evidence backing them up, and thus I can respond with standard gadgetbahn criticisms.
