I consider that an issue with the software quality, not with the update mechanism. The bug would still have been introduced even if it required a trip to the dealer to plug in a programming cable.

At least, when it's updated by a dealer and a cable, you know when to expect changed behavior. With OTA, the vehicle's driving behavior could (and has) quite literally change overnight.

I'm pretty sure you still need manual confirmation in the car, and it shows you patch notes when you next get in, so you should have reason to expect changed behavior.

The only problem I can see with the OTA updates is that they remove the need for physical access to the car. This is very convenient and allows for fast updates but it does slightly decrease the security and lowers the bar for successfully hacking the car remotely.

That same bug could have been introduced whether or not the update was OTA. At least they could fix it OTA as well...!
