Feature Request: Smarter routing based on upcoming traffic lights

[CapheDa]

I’d love to see Tesla add a small but meaningful routing improvement that should be doable with software only.
When there are two possible routes to a destination that both show the same ETA, the car should look at the first major route decision point and factor in the actual traffic light states there. Tesla already knows the routes and the light colors, so if one option has a green (or is about to turn green) and the other is red, it should bias toward the route with the green light.

In Orange County, CA, this can easily turn into a 2–3 minute swing just from how you hit that first set of lights. Today, my Cybertruck will sometimes leave a lane with a green light to move into a left-turn lane that’s red, even though going straight would have been faster in real life, despite the map showing the same ETA.

The idea is simple: when ETAs are effectively tied, prefer the path where the first signal is green or about to go green, instead of blindly following the “default” route. It would make the ETA more realistic and make the car feel a lot smarter in day-to-day driving.

lets just start with smarter routing.

I recently had to disengage for the first time after an 1100 mile drive because of this. FSD tried to make a left turn where there was no light and the road was extremely busy. After waiting for 10 minutes I took over, drove one block to a light, and made the left. I hope this kind of thing is solved with the large model FSD

It will be interesting to see if CarPlay integration gives us access to other maps for navigation.
