I was thinking about this some more, and realized also that comparing bugfixing in software to car repairs is a false comparison. When repairing a car, the work is about identifying the ways it differs from the original design, and fixing those (typically by swapping out broken pieces for identical working ones, or cleaning out gunk). But repairing a bug is not similar to that. It is instead about identifying what is wrong in the original design itself, and how to change the design to eliminate this flaw while not introducing others. This is not like replacing a cracked exhaust pipe, it's like figuring out that the engine isn't getting enough power because the shape of the exhaust isn't appropriate, figuring out the better shape that also fits in the existing fittings, casting a new exhaust with that shape, and then installing it, and making sure you haven't broken some other property. That is all going to cost a heck of a lot more than the typical car repair, and is going to be well beyond what the majority of shops can do. Interestingly, these kinds of services do exist to some extent (the "pimp my ride" style), but they are far fewer and more expensive than car repairs, and few people have ever used one.
