Stalled in the Mojave desert 106F in the heat of the day, a 2011 VW decided all three keys were ' not in range'. Two hours later I reached water, tow truck and ride 67 miles to civilization. It remains to this day whether the memory was wiped clean from extra-terrestial sunspot activity, fault ECU or programmed to lock-out the car at specified date/mileage.
Lexus' judgement renders the ECU behavior to be the vehicle ' owner' responsibility in California. So there's definitely a need to get tools, connections and programs on our cellphones to view logs at the very least. Programmer's are paid to build functionality. The liability unfortunately seems to rest with the end users.
