The Adaptive Cruise on my Alltrack is fantastic. Because I have a bad foot, I use it as much as possible and enjoy controlling speed, even around town, with my left thumb.There certainly is a sales tax on cars sold in the U.S., and lots of cars sold in the U.S. are equipped with DSGs, including various vehicles from Audi/VW that are sold here. I don't know about the parking systems and radar cruise control comparisons, but I hadn't heard that those offered on vehicles sold in the U.S. are inferior, until I read your comment.
On our Tiguan it’s not quite as good, but still works well. On the 2021.5 Atlas I test drove for a day, it seemed to react more abruptly.
Only my Alltrack has automatic parking and it gets closer to the curb than I could do manually, so I can’t complain.
