You would think it would be standard on a Rover by now but it isn't.... it was extremely difficult to find on Discos. My 2013 Lincoln had it and unless you bought the two row fleet taxi, it came with it. But it isn’t really a safety feature as much as a convenience feature... and I won’t buy a Daily driven vehicle without it now.

 

Adaptive cruise is not standard on these trims. It can be added as a stand-alone-option for $1200

 

It was standard in the 2020 built X but not In the 2021 X.

 

I have a 2020 SE with adaptive cruise control, and have used it a bunch. In the 2021 models, you can add it to the base trim for $1200.
