How do they know where to drive?
It’s a toll plaza.
Not a normal highway.
How do they know where to drive?
From my experience riding in Chinese taxis, the lane lines are irrelevant anyway - their preferred tactic is to drive straddling the line at about 20 mph faster than the flow of traffic, then when another car appears ahead quickly cut left or right depending on which lane that car is in. :)
Simple. Drive where the other vehicles aren’t.
If you zoom in there are no stripes, but you already know they can’t drive. (And yes, my wife is Chinese, I’ve been to China, and you think they drive bad here? Ha. Go there once...)
Uhh, they are there. They go up and down! If you look hard you can see them.
PS. This looks like the border crossing into the US, from Mexico in San Diego! lol
