Tickets from SFO to LAX can be cheaper, but that's usually not for optimal times. Sure you can get a round trip ticket for $80, but you'll be leaving at 6 in the morning or something like that. Additionally, you'll have to go through security, not be able to bring your own beverage (or water), sit on a much smaller seat, and not have Wi-Fi.

In other words, I think $95 one way on an extremely punctual bullet train with high availability is a steal.
