This is utterly horrifying.
Even if Tesla owners opting into this beta test are willing to put their lives on the, uh, line, I'm not sure everyone else on the road is as keen as they are to be volunteered into this test.
I'm not sure I understand how other posters are watching this video, and are concluding that the FSD system is being 'overly cautious'. To me, it looks like it's doing its best to get T-boned.
