It's too time consuming and impractical. I'd never get anything done if I was dependent on a train or bus schedule.
...That would be a last resort method of transportation for me. Maybe when I retire, or for weekend train rides just for fun, when I have a lot of extra time.
Last time I took a train to San Juan Capistrano, I waited 45 minutes for the last train, only to realize that I was looking at the "weekend schedule" and the last train had already come and gone. I ended up taking an Uber home. In the end, we wasted almost 2 hours waiting, and our legs were sore from walking, and I had chafing on my inner thigh.
