I found multiple driving scenes in this episode, which appear multiple times in later episodes.

I found location #4 on a filming location website:
http://antelope-valley-film-office.hollywoodserve.com/
It appears as one of the background images:
The above locations and many desert scenes in other KR episodes were also filmed
in this region (east of the Antelope Valley). It makes sense because TV or movie
production must get approval to film at certain locations. Searching filming location
databases may reveal other KR locations not yet found!
