I think it would be great to add ADAS like AEB and or adaptive cruise control to modern cars by modifying driving AI. I found cruise control button in steering wheel of Etk 800, K serise and Vivace. It will be more realistic.
Yes, that would be actually awesome, you could simulate road trips on the Endless Highway, or Utah Highway. I also think it would be cool to add an automatic braking function that you could turn on and off with a button where the engine on/off is. It would be integrated into more modern cars and when a car gets to close to another car or object, it would slow down, and then slam the brakes.
