Yeah, it's going to require being at the station on time, just like we used to have to be at school on time. But I'm sure most people would keep a car as backup.
I think you might've misunderstood. What I'm talking about is if you take the train to work and something comes up to where you can't leave work right at five, you're going to be stuck in downtown Seattle with no way home. Except a nightmare 2 1/2-hour bus ride or an unholy expensive cab trip.
