> Tesla should have detailed maps of this big roads

Their imminent software update adds exactly that. They took their navigation data in house because the atuff they used before wasn't detailed enough.

I mean the maps data they collect from the other Tesla cars and not the GPS navigation, they said that in that accident a big number of Tesla cars pass that point daily and they also collected this navigation data for training, so I assumed they have this detailed maps and the car should know what to expect(I am sure this is a hard problem ) but maybe they need to be more cautious when there is a mismatch(like if 2000 cars used this side of the road but now it appears some line appeared that does not match, lets safely slow down and ask the driver to take over and analyze what is wrong)
