> Well Tesla does it and their customers love waiting hours for software updates (I'm not being sarcastic, this is literally what we found through benchmarking)

I've done several OTAs on a Tesla. Most were about 1 month apart, and my longest update took 28 minutes. The average is closer to 15.

> Tesla can do it because they are sinking money and only have a few hundred thousand cars.

I won't get into whether they are sinking money, but they have about 1.6 million cars.

How does it work? Is it automatic during the night when the car is parked and you're asleep (that would be ideal) or does it updates when you start the car and would be ready to go (that would be a nightmare)? Maybe something in between.

You get an update prompt on screen (and on your phone). The car asks you to schedule a time to install (normally 1 AM) or allows you to update immediately.

When an update is triggered (manually or on a timer) you get a 2-minute countdown to restart and then it will install.

So “we had to call an ambulance because the car was installing updates” is a real potential scenario?

Interesting. My Model X always estimates 25 but it's usually closer to an hour.
