The planned capacity is however only 4400 people per hour for the CES tunnel so about 14s spacing (some other projects even lower). One train every 90s has a capacity of more than 10000 people (and that's not even rush hour with any people standing). Sub-2 second spacing is quite unlikely to be used, since stopping distance (with 0 reaction time, which is not too unreasonable with LIDAR/RADAR) dictates around 2s spacing between vehicles (1.9s at 100km/h for teslas I believe). And while humans might be fine with ignoring safety aspects computers can't and shouldn't. Nevermind that building a subway-light vehicles (more similar to a people mover) is not really the same thing as using slightly-modified Teslas as subway replacement (which is what it seems they will be using for now)..
