But, the thing is, the train trip into the city is 1 hour, and the drive is 30 minutes. And the train schedule is dictated by people who work 8 hours in the office; taking an off-schedule train is a much worse proposition. So even though I gain the time on the train (which is probably not as valuable as I think it is) I still lose out on the rest of my life for having 1 hour less per day to spend completely electively.
So, yeah, I'd like it if my car drove me into work so I was free to do other things. But I would still value a 30 minute autonomous drive much more highly than a 1 hour autonomous drive.
No - it's impossible to work on a rattly, wobbly old train, standing up, or crushed into a seat with some guy's elbow digging into you. You can barely read a book or Kindle on there, let alone whip out a netbook and work. So it's just wasted time every day.
It does make for a very long day though. Between driving to my home station, taking the shuttle from the station to the office, the actual commute, etc, I'm up at 5:30am and get home at 6:45pm.
Connectivity is an issue too. Amtraks spotty wifi is fine for browsing -- queue up a bunch of tabs when the signal is good -- but it's terrible for anything else. Forget about ssh sessions or transferring large files or anything like that.
