How many cars are needed

Can the roughly 1000 people per minute board the metro in a minute?

Usually these systems rely on people getting on/off at different stops, rather than one stop seeing full volume. If it’s one stop, chances are it’ll look like a terminus station and you’ll need several platforms and possibly dual-side boarding to each train. It’ll be quite a bit wider than tracks with no station, or a minimalist station.

This is pretty common at major sports arenas.

The same of course applies to other transit options: high-capacity bus stops take up space, and motorway interchanges and especially carparks also take up a lot of space.

If you want to account for boarding platforms in the metro example, you also have to account for the parking in the car example to make a reasonably fair comparison.
