i think self driving teslas in small tunnels is a pretty workable idea imo i don’t get the 45 degree caltrain wtf

Workable ? Yes. With useful passenger throughput? No it really isn’t.

not sure what gives you the confidence to say that honestly, if you can control all the vehicles in the tunnels electronically you can have higher speeds than a road, maybe 3x

It’s not about the speed of the vehicles. It’s about throughput of the system. The vehicles are too small. The required dwell times too high. The system has like 5 Herbies even before a breakdown of any kind.

again, i see why you might think that but not why you have confidence. in fact onramping and off ramping seem like they could be more effectively managed than in a conventional subway in many instances

My confidence is based on reading train people’s analysis on this. And also the fact that it will neither be speedy nor high capacity vehicles. https://www.google.com/amp/s/amp.cnn.com/cnn/2020/06/12/business/vegas-musk-boring-company/index.html …

have read similar... was unconvinced! they seem to be searching for reasons it won’t work — 1 ply into innovation and stop. you usually see with with incumbents

Almost all of Musk’s tunnel ideas ignore how hard it is to get people In and out of vehicles and necessary spacing for safety. The LV tunnel at least isn’t crazy complicated like the LA master plan. So it can *work* I agree. But outpoint a higher capacity system, I doubt

these just don’t seem like the scale of problems that people make it out to. you can do input output in so many ways *because* of individual vehicles. as for spacing you don’t need very wide spacing at low speeds, or at higher speeds under computer control in a tunnel

Let’s say you can run 60 vehicles per hour and each can carry 5 people. There are only about 4-5 useful hours in a convention day where people move. You’re at 1200-1500. (Note that initially it has human drivers and off-the-shelf Teslas. Even 60 an hour seems unlikely)

ok, these are not generous assumption and #s still higher than their est

I like and respect you. I’m also confident this system will deliver remarkably little utility. As even the mildest disagreement these days tends to end most relationships, I will say we will see and leave the optimism to you
