Well first let me just link the facts
https://en.wikipedia.org/wiki/List_of_autonomous_car_fatalities
There are a TOTAL of 4 semi-autonomous vehicle fatalities, all of which are the result of driver error after being warned by the vehicle to pay attention, hence why they are called semi-autonomous. I'd advise you stop the hyperbole, because it's only making your opinion further from the facts.
Incorrect. The only thing autonomous cars change is that they allow people to have the option of transportation without a license or even without ownership of a vehicle. Nothing changes for you. All you are doing is projecting your fears onto new technology and trying to bring down others with you. That is evident from you throwing labels around like "liberal", because for you generalizing and dehumanizing is one of the ways you fight those fears.
Clearly the idea of technological advance was missed. Giving up menial tasks once thought essential isn't a loss at all. You are like the farmer who sows and reaps his fields by hand in the modern area. Oh wait, there aren't any of those left because the job has been made safer and easier thanks to technology.
So LED bulbs require maintenance? Nope, there are many components that are designed to be maintenance free. For example un-serviceable parts like power supplies. No, I'm not seeing anything in an autonomous vehicle that would require worrisome maintenance. If anything cars of the potentially close future will require less maintenance once most cars are electric. As you said "The more complicated they are, the easier they break" and electric cars have far fewer moving parts and / or parts in general. Of course that's a gross oversimplification, as non moving non mechanical parts require far less maintenance which is exactly what electric autonomous vehicles will be.
If you really are the mechanic / IT admin you claim to be, let's see you backup your opinion with some data. Otherwise you've simply stated more conjecture and as I said before that which is submitted without evidence can be dismissed likewise.

Not exactly autonomous car camera failure rates but there are 0 studies out so I thought I'd be generous and grab non-rugged camera failure rates.
"Take a look at our reliability findings. For point-and-shoot cameras, the median estimated failure rate by the third year of ownership was only 5 percent. And for interchangeable-lens cameras (SLRs and mirrorless models), that rate was just 4 percent.
By contrast, the estimated failure rate for laptops by the third year of ownership ranges from 17 to 33 percent."
That's considering the first 3 years are when it's most likely to break, failure rates drop off after the 3rd year.
Mechanics don't touch most of the Autonomous features. They use the car's built in computer to run diagnostics and simply replace any broken parts. Electrical components, cameras, and the LIDAR aren't "tuned" by the mechanics. That's a ridiculous assertion and would require them to know not only the software systems but also have an electrical engineering degree which isn't up the alley of 99% of mechanics. I can't say I'm shedding tears for mechanics who have to adapted to a shifting market, that's just the way life is.
Stereo system have nothing to do with autonomous cars nor have I ever experienced a catastrophic stereo failure. At most intermittent sound loss. The statement that car manufacturers can't get bluetooth or stereos systems to work is an example of gross hyperbole. In the rare case of bluetooth issues, it's likely a problem with the user's phone not liking the car's bluetooth transmitter / receiver which can happen with any device. Notwithstanding, the rate at which this happens is very low and it's only getting better over time. There's a big difference though with getting a bunch of random devices working with the car and a car's autonomous vehicle systems, which are put together by the auto manufacturer and their potential software partner. In other words, in the case of Bluetooth the auto maker does not have complete control of every device in the chain while it does in the case of it's autonomous vehicles. Like I said earlier though, modern cars already have these features, autonomous or not.
If you are so worried about safety as you claim to be, shouldn't you be shooting for laws that keep autonomous cars on private / low traffic roads until they meet a certain quality threshold and then slowly introduce them into regular roads? After all, autonomous cars have the goal of making roads more safe and making transportation more accessible. I'm all fine with making sure they are up to snuff before putting then into mass use. You can still drive without issue and other people can reap the benefits the autonomous vehicles if they wish.
Regardless, thank you for the opportunity to change people's minds on the autonomous vehicle debate.
