I could be wrong, but I understood that with the first Tesla crash death, it had issues because of too much light (was facing the sun) so apparently also another issue is sensors being blinded.

It doesn't.

Snow is also a problem for several reasons. Also, roads where the painted lines are so faded as to make a poor contrast with surrounding features.

I've also had a lane sensor that worked well during the day, but was confused by the taillights of vehicles that passed me at night, apparently thinking that was the new left boundary and so warning me I was out of the lane on the right.

I have trouble with snow.

a car of yours with lane detection or you personally?

It claims to be 'Simple' lane detection - it is not claiming to be robust or exhaustive.
