Driver profiles seem like a terrible answer to the question of choosing a maximum speed, both for the driver of the vehicle, and for Tesla — because it shifts the understanding of the car's behaviour from the driver to Tesla. I think it's insane that Tesla would take that risk.
IMHO, it's okay for the driver profiles to affect everything other than max speed, including aggressiveness of acceleration and propensity to change lanes. But since exceeding speed limits is "technically" breaking the law, the default behaviour of FSD should be to strictly obey speed limits, and drivers should be given a set of sliders to manually override speed limits. Perhaps like a graphic EQ with sliders for every 10 MPH where you can manually input decide how many MPH over that limit is acceptable.
This would be an inelegant interface, and intentionally so. Drivers should be fully in control of the decision to exceed the speed limit, and by how much. FSD should drive like a hard-nosed driving instructor unless the driver gives unambiguous permission to do otherwise.
[0] Note that I am describing this based on my understanding of the US environment. I am Australian, and our speed limits are strictly enforced at the posted speed, without exception. On any road, you should expect a fine if going 3—6 km/h [2—4 MPH] and caught by a fixed or mobile camera. This applies literally anywhere, including highways. By contrast in the USA, I understand that 5—10 MPH on highways has been socially normalised, and law enforcement generally disregards it.)
