If you decide to swerve, the additional weight at the front will help you to initiate the turn, and good systems will then reduce the braking force at the right moment to give you the most traction when cornering.
- Driving from Tahoe to SF where the limited lane visibility due to the slope and a slight twist made the system think I was going to hit the car I was overtaking (from the 2nd and left-most lane). This really felt dangerous since it activated mid-turn and messed with the car's balance.
- The other event was a roundabout where a car yielding to get in behind plants jump-scared the breaking system. At 10-15 mph or so the unexpected breaking wasn't dangerous though, worst-case scenario you get rear ended at low speeds.
Beyond that, overtakes where you slow down as you return to your lane may trip the system, but those cases are fair even though the following distance they intend is a bit too cautious. I reckon my Mom would be holding the roof with both hands if she was there, but my Dad & siblings unfazed.
I did find "normal" mode on the Model 3 was way too sensitive, but I set it to "late" and it's been fine ever since.
