You are in the minority of drivers. Most people want updated tech in their cars, including (what I consider to be) very valuable backup cameras. I'm shocked to see this sentiment about "dumb" vehicles rising on HN.
I don't agree with the backup camera take (I love mine), but I otherwise generally agree with the dumb car comment. I want my vehicle to be understandable and hackable, so I can work on it without needing access to its computer as much as possible. I don't want aspects of my vehicle to be made available on the public internet. I don't want a touch screen that eliminates tactile controls.
