Someone correct me but with the Tesla if your not in self drive and you just take your foot off the gas the brake comes on immediately. Obviously because your one petal driving. On a regular gas car the brake long only comes on when you hit the brake. So right off the bat I would expect Tesla vs ICE to trigger the brakes more often. With FSD it’s been my experience that the car uses the brakes a lot more - phantom braking example. That plus FSD putting on turn signals, then right on, then on again or going left but with a right turn signal on.
Now this specific incident likely has nothing to do with my comments above. But my point is that Tesla (and EV and other one petal cars) can be confusing and frustrating to regular drivers. Add in FSD and that makes it even more so. I can tell this by how other drivers respond to my FSD and how YouTubes show others responding.
FSD just doesn’t drive like a regular driver in an ICE car. If the driver behind is impatient I can see how more accidents happen this way. It’s not (necessarily) the Mercedes fault but you can see how it’s irregularities could contribute to the likelihood of it happening.
