Hard to say as I don't see phantom braking being the biggest issue with AP, but my Model 3 has radar.
In fact over the last 2000+ miles of traveling with AP I have had any non-maps caused phantom braking event. This is saying a lot as I used to be a complainer about phantom braking.
Now I have turned off things like traffic light/sign response (part of FSD), and NoA (part of FSD).
It also doesn't rule out phantom braking becoming an issue again.
Personally I'd probably go for a non-Tesla EV over a Tesla due to the lack of customer support with Tesla, and inconsistency with build quality.
