Don’t know how highway assist was doing it? But it worked.
So I was driving on Grand Central Parkway in NYC yesterday using HA and we came to a newly paved section. 2-3 miles.
On this section there were no painted lines, both the solid line for the shoulder and the dashed line between lanes wasn’t painted yet. Only the little tags to show where the paint truck should paint every 40-50 feet.
HA didn’t seem to mind, even with curves, somehow it managed to steer, lane center, and follow the car in front!
My Maserati always freaks out when it loses the lines.
