I was going off of my parents experience replacing small electrical things on their new car. In their experience, the labor for that has been expensive, regardless of how cheap the part was. If all the little bits and bobs for each model available and easily-replaceable, that's radical. I also wish there were fewer lightbulbs to replace on my car, but that can be my own problem.
Oh yeah, man. Yeah. I like to pay top dollar for labor rates, because I find it cheaper (eg $100/hr gets things done twice as fast as $70/hr, and nothing ever has to come in twice for the same problem) but that's absolute murder for the small stuff. I had a good shop back in new england where they knew me, and my parents, as decade+ customers, so they wouldn't charge for a two-minute bulb replacement. Out here, I've taken those duties on myself. I replaced my rearview mirror, light switch, and tail light yesterday night - would probably cost me $200+ in labor to get it done.
How easy it is to replace the little things depends on the car. Some things are easy in some cars; some are not. For me to change my spark plugs, for example, one has to lift the engine up - $200 labor, $100 for six high-quality plugs and wires that will last long enough to not pay another $200 labor anytime soon. On the other hand, tail lights don't even require tools to replace. Similarly, ultrasonic sensors might be incredibly easy, or they might cost you enough that you're better off replacing them all if one goes haywire, because it only adds 5% to the cost.
Tesla offers a service plan at $600/year. Basically an extended service warranty. I would pay $600/year in a heartbeat for the service. I pay significantly more for my (admittedly aging) car. Yes, you can buy a whole new $600 car every year that will probably last a year, but I use my car as more than a tool to get from A to B. In fact, that's one of the reasons I won't be buying a tesla any time soon - a lot of people have "range anxiety" but almost nobody actually drives far enough for it to be an issue. But until there are charging stations every hundred miles along every road in Alaska, BC, Alberta, the Yukon, the northwest territories... it's a dealbreaker for me. I can't carry spare electric charge, but eight extra gallons of gas gets me a very long distance. It sounds like a bullshit example but twice a year I find myself far away enough from civilization that a 500-person town gets signs pointed to it from 150 miles away. Or 500.
Back to the topic - I love the safety features. Are they hand-holding, baby bullshit? I don't know, people said the same thing about seatbelts. "I don't need no gubment telling me what to do, I'll get thrown clear if I crash anyways, it happened to a guy I heard about." Look at modern cars - they ensure the survival of absolutely insane crashes; the cars smash to shit but the passenger cabins stay intact. Lane assist is bullshit until the one time you're so tired you drift into a microsleep. Automatic braking is bullshit until you come around a corner into a traffic jam while you're glancing at your passenger. Backup cameras are... well, never bullshit; they add to the cost but they're an excellent complement to your mirrors, showing you blind spots. Ditto blind spot detectors. How the fuck are people complaining about fewer blind spots? Because it's electronic and can break? So? As if solid steel doesn't break. Yes, we all love classic muscle, but the truth is that the only people I trust driving classic muscle are the ones who are able to seek it out, afford to buy it, and afford to maintain and/or restore it. Which is great, because the barrier to entry is high enough that you don't get Little Sally or Bobby driving daddy's 60s charger after getting their license, not realizing it has 500 hp and about as much torque and jumps at the slightest touch. I'd prefer they drive the car with lane assist and auto braking. Ditto for soccer mom and ditto for tired dad and so on.
If you don't like modern safety features, classic muscle cars are fairly inexpensive to buy - you can buy many very nice cars for $5-10k. It's got just enough electronics to power the lights and spark plugs and starter motor. Buy that.
