Electronics can experience soft errors but that's usually not too much of an issue with any sort of redundancy. That's why you don't do what Boeing did with the 737 max and sell a single sensor to customers.... From my understanding the ACAS system wasn't so much the issue as just the single sensor, lack of flight training simulator time, and lack of proper documentation. I don't know what they did to the ACAS system but I believe it's significantly less "error" prone.
So how do you feel about the hydraulic and vacuum systems that control most automotive brakes? The electrical systems eventually still have to move a physical linkage... it's just done with solenoids instead of some fabricated bracket/linkage. Modern cars are still significantly more reliable, safer, easier to drive, and more powerful due to electronics.
Tow? Who tows a car anymore? Put it on a flatbed and be done with it. That being said I'm sure there's still some physical way to put it in neutral.
