It's worth noting that Subaru vehicles have been doing vision-only adaptive cruise / lane keeping / emergency braking for many years, which they brand Eyesight. In my personal experience its adaptive cruise is as good or better than most other cars I've driven which use radar.

(Admittedly the reasons why the Subaru impressed me was more for its programming rather than absolute precision. I liked how smoothly it transitioned between following and open road ahead. Much less jerky.)

Long term: Vision is better, and less prone to false errors (see all the talk of phantom breaking).

I think it was on the way out by maybe 2022

Short term: Global chip shortage made supply tight, and it was either remove it and rush out with the no radar code branch, or stop shipping cars.

Long term I think it's a fine decision, but short term it's kind of a big thing to rush.
