Similar experience. NYC to the Adirondacks and back with ZERO interventions. Also navigated local roads using UHF a bunch and performance was great. The system does occasionally get confused by lanes ending or splitting, but I know to expect and anticipate taking over.
Just triangular cones. Right now it’s pretty useless as-is, though. The system basically just identifies them, but does nothing to navigate in way of them. The vehicle will not veer away from the cones, and will run them over if allowed to.
I’ve got a spare set of oem silver with one key (cannot for the life of me remember where I put the other) Never been used, however they’re out of the box. I’m in NE NJ. I’m looking to get $500 for em. I just have not gotten around to posting them yet. (Lazy bastard)
