I find it very scarey that I have to wait for a software update to be applied before I can drive the car.. I hope there is an override mechanism to allow the car to start anyways in the event that software update fails.
The software updates would be for the infotainment (hate that word) or navigation system, not the control systems that actually run the transportation part of the car.
ECU updates that are normally done by your dealer could in theory be done OTA like that. So, 10 minutes of 'down time' instead of a trip to the dealer and an hour+ of down time.
Seems like something that you'd want triggered while you plug in/refuel; when your car obviously isn't going anywhere for a few minutes. And using tricks like Chrome OS has (a/b partitions for current/update) could shove the actual downtime to not much longer than a reboot takes (hopefully seconds)
