See above comment, why does the number of vehicles matter? I've left stadium events via taxi and ride-share, often there is a queueing area where cars pull up, you get in and leave. It's like a train that takes you home.

Oh no. The number of vehicles carrying 1-2 passengers through a bottleneck that is entry/exit to the venue doesn't matter at all.

Even though it's a trivial question of capacity and throughput.

A really sloppy, inefficient train.
