This feature is also available in "cheaper" cars. My Kia Niro has is, and although I didn't get a chance to make "full" use of this (thankfully), I did incur the "too close" beep which prompted me to break one time I was not paying the road the attention it deserved. As a side note, with auto distance keeping cruise control, lane assist that actually moves the wheel to keep me in lane, side radar that alerts if a car is coming as I try to switch lanes and the AEB, this is great entry into autonomous driving (as far as some core systems that are actually in commercial use already).
