It might be fixable in software. I'm a bit annoyed at Tesla for over reliance over painted lines. They fade, they can be covered, be outdated ..
That old fail video of a SDV stuck inside a circle is not funny anymore.
Off topic: I never understood why this video was discussed that much, especially in order to blame SDVs. It's an example of pointless road markings and a perfectly behaving vehicle. It's like driving into a one way street that turns out to have no exit. The driver can't be blamed.
We'd expect at least 'cycle' detection ;)
