For the sake of playing devil's advocate, many of the examples of going through bus lanes and FSD issues in general use the old hw3 hardware. Hw3 is no longer supported and doesn't get updates anymore. Anything new should use hw5 which is more advanced and has much better support. Hw4 solved many of these issues.
Hw3 FSD is good, but it still has some edge cases which don't work such as bus lanes, using express lanes, etc.
I agree that anything unsafe shouldn't be on sale. it's a tough one. i see tons of content implying FSD is completely incapable of self driving where as the reality is now they are down to solving the truly hard parts of chasing edge cases. Ideally there should be another decade of work yet before anything goes on the roads just to be sure, and that would also need detailed regulations for support, recording etc.
