> Standard subway systems have to have much more in regards to fire suppression than just ventilation. The entire tunnel has to be protected from fire damage with insulation, some tunnels have sprinkler systems, etc. These wouldn't be needed in the dugout tunnel.
No they don't. There's no insulation for underground tunnels for subways; just steel liners and reinforced concrete, at least according to NFPA 130. No sprinkler systems. So no difference here.
> LV vs HV
Yes, true. HV cables and other supporting systems are more expensive. So the only difference here is batteries, which are far more combustible than cables in concrete.
> LIDAR cameras
Correct me if I'm wrong, but to my knowledge, Tesla has removed LIDAR-based cameras in their lineup.
> There are also automated subway systems all over the world that don't depend on the tunnels being lit, and they don't seem to have any issue avoiding collisions.
Yes, I know. And those trains communicate via access points placed on the tracks, each of which are run with fibre and power cables. Now that bare tunnel is no longer bare.
> incline
Sure, it's more flexible. It still doesn't address the claim that this will help make those tunnels cheaper.
