He has a point though... Cars are manufactured in such way that when something fails, the failure is not catastrophic. Car might not be operational, but it is very rare that malfunction causes a crash. With SW I'm not convinced that the same can be accomplished. If you add 3rd party maintainers to the mix, it gets even worse.
I still think the right to repair is worth the risk, just pointing out that it's not so clear cut.
The mechanic's professional responsibility is to repair the car. If we're assuming they are too ignorant to do that job, then why go to a third party mechanic in the first place?
