Chain rings do not like pant legs. Not to mention all that black grease on the chain.

It's turning into a lot of hassle for a small amount of on-bike time. Though being stuck at work with no car and everything a mile or two away isn't any fun either; at least with a bike I can go out to lunch.. if I want to hassle getting changed. On the other hand, paying for lunch all the time is expensive; I should bring sushi.

Geeze, 120mph? Too fast. Train ride is nicer, but yeah when the train fails it fails spectacularly. Light rail here is the same way, it's either running or it's not but when it runs it runs on time. I mean it's not Japan, but you could reasonably set your watch by the rail to within a minute or two.
