I prefer to stay in one place all the time, so I don’t have to deal with any sort of conveyance.
The GPS devices will only end up “broken”… just like the card readers in every cab in the entire city of Chicago are “broken”. Goddamn, I hate taxis. (Here’s a tip, though — ask if the driver accepts credit cards before getting into the cab. He will say yes. When he then insists that the reader is broken, without even checking it, when you get to wherever you’re going… tell him to go fuck himself. Free ride! Well, if you don’t value your bodily integrity etc. etc.)
