FSD should be able to auto switch “Use HOV”, the car knows exactly how many seats are occupied.
I should not have to manually enable “use HOV” when I have a passenger. I’m usually driving by myself but today I had a passenger and I was on the interstate driving manually and got in the carpool lane and enabled FSD. The car immediately signaled to leave the carpool lane. I canceled with the turn signal. It did it 3 more times right away and I finally tapped the brake. I realized several minutes later it was because I have “use HOV lanes” off because I am alone mostly. Digging through the UI to fix this while driving is not great.
The car absolutely knows how many people are in the car and it obviously knows where the HOV lanes are. I suspect the map data even indicates 2 or 3 people requirements.
