Friend in Seattle had this experience when trying to use a zipcar truck out of a garage while moving (i.e. Limited time window to get stuff out of one area to another). Ended up calling support, dealing with multiple hours of delays. Despite the issues which has led him to avoid Zipcar these days, he uses ReachNow (now defunct) and car2go (now called ShareNow) regularly and AFAIK ReachNow didn't have these limitations when on long out-of-range trips - they solved the problem by doing sortof a two-factor of having an RFID card (to unlock, on window) and a pin code (entered via the BMW iDrive system to start engine).<p>I could argue Zipcar has a deep integration problem needed to solve the out-of-comms scenario. They try to support several car vendors in order to have different car types (toyotas, mercedes, ford vans) which limits them to having this cellular-dependent setup. Whereas Reachnow (BMW), car2go / Sharenow (mercedes / smart), and limepod (fiat, for now) have limit the car type for better integration.<p>In a related front, a friend moved into an apartment building with some bluetooth-based laundry vending machines. The machine requires blootooth, and the payment is done via phone which requires a cellular connection. The laundry room (like any basement area) has a spotty cell connecition, so the friend does some weird positioning exercise to find the area where he can have a cellular connection while still being connected over bluetooth to the laundry machine. Strange future.
