That's literally the best possible result though. The only alternatives I can think of are using the military's encrypted gps, or tesla launching their own encrypted GPS satellite network. .. neither of which seem like realistic options. If you have a way to navigate cars without GPS, you should probably contact Tesla so you can make millions of dollars.
