It really is the least talked about benefit to public transport, yet is so significant. Sure you can't do too much but you can watch a show/movie, play a game, read, write, draw or even do your taxes and shop from your phone and laptop.

Certainly can't do that driving around. And it let's you relax and change from work mode to home mode. Even if you have to do a little drive to and from the station.

Plus like you mentioned, less chance of delays and being involved in accidents. Win win win win.
