I have talked with someone else who didn't seem to have a card, so maybe it is now optional? It was admittedly a really annoying--if totally understandable--delay when I first went to use the service, and they probably lose a ton of customers who would otherwise impulse buy their way into their first ride were it not for "and now wait forever for your card to arrive". The card definitely solves this problem, though, as as far as I can tell the car does have local storage for how long you are allowed to unlock it. (Your big problem is if you then get back to the car late and the car re-locks. It has no concept of being home or being done other than your time as determined by the service when you last talked to it is up.)
