I mean, most people don’t think ease of changing a light bulb (that they never have to do) is a deal breaker for a car. I haven’t had to change a headlight since they went to LEDs. My last car that was 7 years of owning it.
I think we should insist on making things repairable, but should focus on the things that come up frequently.
Because everything is a tradeoff, things like how often it is likely to need repair, how much the car costs, functionality of the car day to day, looks, gas mileage, heck a lot of stuff will come before a once a decade thing that you’re either going to pay a shop to do or trade before it’s an issue.
