Thanks everyone!
Many of the roads we are planning are two lane with posted speed from 45 to mostly 55 in Arizona, New Mexico and Utah. Once we start I think we're committed to the trip. Has
@Bill55 made his trip yet? I may have missed posts.
It was actually conditions that are not likely to occur again but it's good to know. I engaged ACC to see how it worked and soon after the SA wanted me to exit. I sped up to get over to exit but no regen to slow to exit. I just hit the brake.
I've already shared my disappointment about lack of wired connection...
Taking delivery on 19" getting 3.1 at higher speeds than I should be able to do out west is giving me comfort, thanks again.
