Congratulations on the new car. I see you've got your home charging sorted out. Oh, and I particularly like the color.
The only thing that I've ever done about phantom braking is to make sure that nobody is ever tailgating me because if I phantom brake, there's going to be an accident. For phantom braking events that take place on regular trips (e.g. a commute), I just learn which lane to avoid and where.
Note that you'll also see aggressive braking if a car is crossing the road in front of you. There's no chance of you hitting the other car, but your Tesla will be extra safe - and try to hit the car behind you.
Ultimately, the only fix is going to be FSD Beta once they make that the basis of Autopilot. Elon is saying that they'll go to everyone in FSD Beta by the end of the year, but I figure that really means next spring. Then about 6-12 months later they just might switch everyone over to the FSD Beta software at whatever level of service they own. Until then, unwanted braking.
