The Good:
ABS (being able to stop very quickly even on slippery ground is great and prevents accidents – just make sure you don’t brake so fast the person behind you rear-ends you)
Power steering
Good defrost/de-steam and heat and AC
Good radio antenna that doesn’t involve a long fragile metal telescoping rusting thing.
The Bad:
Computer control of driving of car in any way: I hate this and it makes me feel very unsafe, because I program computers and have seen malfunctions, and I don’t want to ever be in a vehicle that is maneuvering based on a malfunctioning computer.
Wi-fi access to vehicle computers: Combined with the above, means a hacker or assassin can remotely cause a car to crash. NO! Horrible, horrible horrible!
Computer tracking of my driving: obviously evil and intrusive. hate hate hate!
Rear-view mirror that changes its reflectivity to match light sensor data, so I don’t need to flip it when bright lights shine from behind. Except it doesn’t work well, and they removed the ability to flip the mirror. Awful awful non-feature that also no doubt cost more for a worse thing.
Headlights that are always on, even in bright sunlight, and can’t be turned off: NO! Does not improve safety. Headlights in drivers’ faces messes with vision. Wastes energy and lightbulbs.
Chirping sound when unlocking car: This should be an OPTION. I mostly don’t want it to chirp when I unlock it.
Voice-activated controls: SO annoying! I end up yelling at them, and hating them. They are slow and annoying and unreliable. They tend to be horribly annoyingly programmed. Give me actual physical controls.
Door locks and starters that don’t even have an actual key & lock: No, I want to be able to physically unlock using a physical key & lock, in case the electronic stuff breaks.
The Ugly:
Computer-controlled headlights: I have this, and the computer broke and flashes high beams randomly. Only repair option is replacement of the $600+ computer. I had my mechanic disconnect the high beams instead. I hate that. I don’t need or want computer-controlled headlights. A wire and switch would work just fine, and if it somehow broke would not cost $600+ to replace, This seems mainly like an excuse to charge more for the car and more for repairs. Awful.
Power windows: Ok, except when it breaks and has to be expensively replaced. Hand cranks can be very easy to use and inexpensive to repair.
Power door locks: Ok, except when it malfunctions and the locks stop working, as has happened to me. Oh look, another reason to buy more parts. Oh look, I can’t refuel my car until I repair the right rear power door locks because they’re all on the same circuit.
Doors that auto-lock after driving a distance: No thanks. Seems like another way to wear out parts so they’ll need to be replaced sooner, especially when opening any non-driver door opens all the locks at once.
Fancy keys that cost $100+ to replace or get copies: Not worth it. I’d rather have a metal key I can replace for $5.
Key that when I try to lock/unlock twice quickly, starts rolling down all the windows, supposedly as some sort of safety feature???: No, all this ever does is accidentally get activated and makes me walk over to the car and close the windows when I was just trying to make sure it was really locked. Often when raining…
Push-button start: no thanks.
Windshield rain sensor: Ok, except it doesn’t work all that well and costs tons more to replace the windshield. Just give me enough different speeds on the manual wiper adjustment.
In-car televisions: No thank you!
Automatic transmission: These strike me as uncontrollable transmissions. I prefer a good European-style manual transmission.
Cruise control: I never use it. Would rather not pay for it.
Butt-warmer: ok.
