Maybe a bit more training needed?

2024 M3 AWD, FSD v14.3.4 + 2026.14.6.12

1. FSD is redirected by cones to another road due to a closure. 2. Failing to realize the road is closed, FSD is so intent to get back to its original route that it fails to reroute to the new road after being diverted. 3. FSD then attempts to cross a double yellow center lane line, attempting to turn left to return to the original route. I intervened by braking, then drove straight until FSD finally rerouted.

In an admittedly difficult and rare scenario, FSD was about to make an illegal turn to get back to a closed road. It would have been interesting to see what FSD would have done had I let it play out and turn left. It would not have been able to turn right at the stop because of the large road closed sign and more cones blocking the lane. It would have had to turn left, then make a U-turn to get back to the closure. It could have gotten caught in a loop.
