FSD profile fine-tuning

This would allow the user to fine-tune how "chill," "standard," and "hurry" behave, and allow for additional settings. This would allow the setting of maximum speeds, minimum speeds, speed differential to justify an automatic pass, lane preference for multi-lane highways, freeways, etiquette for using the fastest lane.

There should also be an "eco" mode that is tuned to try and return the best range... basically trying to achieve the EPA designated range. It could do this not only by driving more slowly and accelerating less aggressively, but also by braking more slowly/gradually toward red lights to increase the odds of still having momentum by the time it turns green. It could also allow for larger gaps in stop and go traffic, so that it can retain as much momentum by helping to smooth the traffic... less braking and accelerating, and more cruising at a relatively constant, slower speed.

There could also be a separate "max speed" setting for when the car is purely accelerating under gravity. In other words, if it is a steep enough decline that the car doesn't need to expend energy to go above the speed limit, it will allow the car to go up to that maximum speed... say 80 mph, where it only allows for up to 65 mph when needing power from the battery.

Additional behaviors/situations to address?
