Earlier quoted context omitted.
Audi calls it adaptive cruise control which I find correctly describes what it does.
"Adaptive cruise control" sounds like the vechicle is just controlling speed based on the car in front. It does not sound like it implies any type of auto-steering.
I think the good think that Tesla does though, is having a simpler package for all of that. German makers can't keep but making 5 different systems that you can (or not) combine so they can charge more $$$.
