Although, that has its own drawbacks! I got used to google maps telling me about service changes on the subway (it's pretty good about warning about planned service changes), and I found myself getting angry at maps when I found out the PATH had a planned service change that maps didn't warn me about.

Unreasonable, yes, I know - but something worth sharing I thought, since if you get into the realm of "transportation data" it's kinda gotta be all-or-nothing, I think.
