There are a few Tesla crashes on camera, and they look like something even a fairly bad driver could avoid. See for example the SF tunnel crash: https://abc7news.com/tesla-sf-bay-bridge-crash-8-car-self-dr...
Besides, other vehicles have now active safety functions that seem to work extremly well. There are car models out there with ZERO fatalities so far thanks to this technology. So FSD being an improvement compared to really bad drivers is not really an improvement.
