LOL, I had considered that, but...with my luck, I would brick my car! I’ll keep that in mind though. I never got around to investigating it..
There are two other developments in cars I really, REALLY like:
1.) GPS
2.) Back up camera
I will say...I force myself not to use the backup camera all the time. I want to remember how to back out without one, but...it is really handy when you are trying to back out of a parking space in a crowded parking lot with limited visiblility. I back out just far enough to pick up traffic in the camera’s wide field of view.
Those things I like.
My car came with blind spot warning, which I love. It also came with the EPA mandated auto-stop/start, which I hate. I hacked the ECU to turn that off permanently. I also permanently turned off the annoying seat belt warning, even though I always wear my seat belt. Auto bright lights on/off were an up charge for my car which I did not pay for. I later learned that the hardware was there, but they wouldn’t enable it without paying an extra $1000 or so. I easily hacked the ECU to turn that on. That is essential as far as I’m concerned. Same with lane assist, which is not essential but I do like. There are another couple of hacks I did that I can’t remember off the top of my head. Audi has a great forum with a lot of smart people and it was pretty easily done by following the instructions in the forum. I never would have attempted any of it without that guidance.
