As a counter point: these Tesla videos are much more common because there are more Teslas driving around with the feature enabled.

We don't know of the Mercedes is as much of a murder machine based on the little material from their FSD system there is.

All self driving car manufacturers have videos of their cars doing the most ridiculous things. It's hard to pick one above the other. At least Mercedes seems to have documented their limitations rather than assumed their system works everywhere, so that's a good sign to me.
