I bought a car recently that has all the collision avoidance, lane change, blah blah blah, and I bloody hate it.
Sure, you can turn most of it off, but...it is only for that driving session. Next time you start up the car, it all comes back on again.
I particularly dislike the collision avoidance. I usually keep good distance, but sometimes...such as when the car in front of you taking a right or left turn (especially a right turn, and they just poke and poke and poke, so you go around them to the left) the damned thing jacks on the brakes.
I have given up, and just press the accelerator through it while it is jamming on the brakes.
There is one single feature I do like though-and that is the adaptive cruise control. I like cruise control, but rarely used it because traffic is often too congested on the highway and it is a pain because you end up having to manually adjust it up and down, which defeats the purpose.
With the adaptive, you set your speed at about 5-10 above the ambient speed, and just get behind someone who is going closer to the speed you like, adjust how far back you want to be, and it works great.
I never take my eyes off the road or car in front of my, and my foot is always poised near the brake, but on long journeys in congested traffic, it works great.
But having a car drive while you read a book or sleep...insanity. Only a blithering idiot would do that.
Depending on what kind of car you have, most of them can probably be permanently turned off by hacking the ECU. I turned off a bunch of stuff on my Audi that I didn't like. I also turned on a bunch of features that I liked, but didn't pay for. :-)
I just bought a used truck that, to save fuel at low power, goes from 8 cylinders to 4. Lots if problems with that. I researched the various blogs and found a guy that would reprogram the computer to turn it off and run V8 all the time.
$50 for him to reprogram my computer AND it included shipping back to me. Granted, it took him probably more time to repack and label the box for my truck’s computer than it did for him to reprogram it - but $50 well spent IMHO.
I’m guessing most anything can be changed with the various sensors and safety features. (My truck was off the warranty so that is a big deal.)
