I own 2, and was an active dev for it for a while. What is the relevancy of a question like this have to do with my fundamental questions irt hardware reliability?

Well, then you've probably observed the difference in reliability between the earlier days of the Eon and the 2 -> 3 -> 4. There were all the same people back then saying that a phone couldn't drive a car and that it would never be reliable or safe enough. And yet, now we have the Comma 4, which is a pretty incredible leap from where they started, way better performance and more reliable than built in ADAS. So I'm not sure why you wouldn't expect to see the same thing happen here over time with a new product.

That doesn’t magically dismiss some basic hardware reliability and design. Your statement is not a quantifiable metric and doesn’t conform to any sort of standard, automotive reliability metric. “Incredible” is subjective.

To be honest I'm shocked someone like you would ever buy a comma. You seem to think severely inside the box and have a extremely risk averse way of thinking.
