And, especially in European cars, car software modification has been aggressively locked down, mostly for emissions compliance, anti-reversing, and warranty reasons. Just like any other device firmware. The "I can modify my own car, so why can't I modify my own device firmware" analogy for firmware really falls over here, honestly, because cars are firmware these days and it's locked down and protected the same way as any other firmware.
