You mean, *LineageOS devices.

Apart from what some commenters already pointed out (about the orientation of the roads there), I’m not sure how it’s going in the US, but in Europe, we have a hierarchy, where the sign on a pole takes precedence over the sign painted on the road.

The hierarchy is:

1. Police officer’s hand signs
2. Traffic lights
3. Signs on a pole
4. Signs painted on the road

According to this, you cannot turn left, even though it looks like a left turning lane.

Is there such a thing in the US?

That’s way too much hassle. I guess, when the anti-adblock kicks in on my devices, I’ll just stop watching YouTube. I have tons of better stuff to do anyway.

OsmAnd is awesome, I use it especially for cycling. It has an awesome cycling/hiking route planner, and even the smallest forest paths are on the map!
