BlueCruise hands free working prior to the OTA updates?
Yes, I hadn't really focused on BCH-F. I finally drove on a known BlueCruise route on September 1st, and hands-free took control. (I remember the date because it was a birthday trip for someone.) Then, I got 3.5.2 on 9/7 according to the app.
It first took control in heavy traffic. I wish I could say I was more impressed. BCHF on my truck seems to favor the lines next to traffic rather than biasing toward right or left sidemarker lines of multi-lane highways. It also seemed very abrubt in varying traffic speeds. Seriously, I can drive a hell of a lot better than that. There is some opinon I have read that jumping from 3.1 to 3.5.2 may have skipped any refinements to 1-pedal, regen, and BC in 3.4. I don't know.
I'm beginning to appreciate the fact that these systems are great checks on driver mistakes and have a better chance of saving my bacon than anything I've ever driven. But, I haven't gotten used to letting go of the wheel and letting the computer closely hug the lane separator lines. Sometimes, I wonder if it's camera alignment, but I think it has built-in self calibration.
