Come on Tesla... You should do the following: As suggested by jasonlingx, have cars update each other. If after a few days this doesn't happen, you need another option. You'll have to go negotiate some deals. First, Comcast has an enormous network of wifi hotspots that their customers create. The per-GB price on this should be very low, particularly if you're willing to be throttled. Second, one of the four major carriers should be willing to work out a deal for extremely cheap data if it's at super off-peak hours, say 2-4am, when there is loads of spare capacity.
