This attitude is why we can't have nice things. You have probably never experienced a system like I outlined and you won't even consider it without adding other requirements that drive up the cost until we cannot get it.

If instead you would accept that you can wait up to five minutes, and "other people" are nice enough and so you can share a space with them - we could have a nice transit system.

The five minute time I used above is not arbitrary. While there is some debate on the exact number, 5 minutes allows for a lot operational things that are really nice.
