> an electric walkway in a dedicated tunnel It's highly unlikely they would work in tunnels, where real estate is even more constrained than at street level, and where the capital investment is substantial. Walkways are a compromise between ingress delay and wait time (at which they kick ass) vs total speed, they only make sense for relatively short runs; you just wouldn't spend tens of millions per mile to double or treble walking speed. But it any case, once you build the Loop network, there is nothing in principle stopping you to retrofit a moving walkway into the tunnels. Your initial retort was more of a reduction ad absurdum "if we don't do this with moving walkways... then surely using Tesla is worse idea". That line of argument simply doesn't work, a system using Tesla can hit two relevant metrics (pphpd and average speed) while the walkway system can hit only one (pphdd), and the good performance on that metric for that does not make up for the latter, especially considering the eye watering costs. The club cars are used for tunnel evacuation, they are not disabled friendly; disabled passengers are handled with a few specialty minivans. So club cars are an unsafe and low autonomy solution that can get the most people out of the tunnel in a few trips, without worrying about speed, crash rating, if the doors open etc. (they have no doors). They would certainly be unacceptable as daily drivers at 40Mph+
