If its computerized...it can be hacked. Currently people are stealing cars by hacking the fobs/security systems/OnStar stuff. Wait till bad actors decide "I'm gonna make that GMC drive into that bridge abutment just for kicks".
No thanks.
I DO like adaptive cruise control on my Grand Cherokee - use it instead of "old" cruise, and it'll use the forward sensors to latch onto a vehicle in front of you and just pace it; all you do is steer. GREAT for trips MD to FL! But, I still have to participate by steering, paying attention, etc. It just takes the "matching speed" guesswork out of trying to pace traffic while resting your foot (and with 2 rods in my legs, my feet definitely can't stay in one position for too long or they go to 'sleep').
