>The 4,500 is based on future hypothetical capacity if the Teslas were replaced with fully autonomous high capacity people movers operating at 155 mph that don't exist.

>Real world it does about 800 persons per hour with peak being around 1,300. Vehicles average around 30 mph but when considering time for loading and unloading it is closer to 12 mph.

>Yes there are routinely traffic jams in the existing tunnel even though it is a single lane going only one way with no branches or merging traffic. Pretty sure the issue is Boring failed to properly simulate how long it takes to load and unload people so the stations become backed up meaning the traffic in the tunnel backs up waiting for an open spot in the station.
