You can look up the nVidia Tegra board on Wikipedia and see for yourself that the "shitty short sighted engineering" board is used in many gasoline cars.
- leggomylibro 7y agoYes, but those ICE cars were designed by engineers who understood that you only get ~100ks of write endurance with this sort of nonvolatile memory. Tesla's use case is unique because they stuff enormous firmware images into the on-board NVM and write to it constantly with very heavy logging. Of course your Flash/EMMC will wear out quickly if you constantly write to it while your device is on - that is the short-sighted part. The board isn't necessarily a problem, but how Tesla chose to use it sounds like a very predictable problem.
