To be fair, Volvo did the same thing recently, so it's not just weird American startups that do this - Volvo never released the numbers on how many cars were affected, but I'm a member of several facebook groups for Volvo owners and it was just like an onslaught, people were posting daily warning others about not applying the latest software patch or it had a good chance of bricking your car. Absolutely no idea how that got released into the wild.
