Ford actually does this. They have something called limp mode for when sensors detect degraded conditions. They won't honor the warranty if you clear the code manually and continue operating the vehicle.

Many cars enter limp mode for when the ECU senses a possibly damaging condition. This limits the performance and capabilities until someone with a diagnostic computer can plug it in. Many times these diagnostic computers are entirely proprietary.

I'm not saying it is justified, but to pretend that other businesses don't do this is silly.

Well, that still wouldn't reduce your car speed by 50%.

And even for that case there would be a warning on the console and a mechanic would be able to inform what is happening. On this iphone case, there was no warning at all on the device nor there was any disclosure that they would be doing this to the phones.

You know this. In either case, thank you for the ECU info.

It reduces your speed by much more than that. Varies depending on the model, but limp mode often won't get you go past 2nd gear.

It does actually. It limits your top speed, and your engines rev range to approximately half of redline or less. Typically you end up limited to under 45. Also, accessories and other options, like A/C are disabled. The only indication that you will get is the reduced performance and the check engine/service light (sort of how you might get a 'service battery' warning and reduced performance on a phone).

Again, not defending it, but pointing out that Apple hardly invented artificially limiting performance behind opaque warnings to prevent unwanted outcomes. Cars have had limp mode since before the iPhone was invented.
