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.
