Very good point
@JRP3. I rarely charge my Roadster to 100% because I rarely need max range. When I do, I've learned to be double careful until it is enabled again, as you become so used to the regen slowing the car as needed most of the time. Likewise when regen is disabled due to low outside temperature. That said, it would be easy for them to program a reminder when an owner overrides the default standard regen to choose more aggressive setting. It reminds you regen will be disabled if SOC is over 90 or 100%, do you still want to set regen to high?
Given the level of SW sophistication built into every facet of Tesla cars (especially Autopilot) there is no reason I can see this should not be simple for them to implement and accommodate owners who appreciate stronger regen braking. I'm not certain but I think MS and MX may have a little less regen than Roadster but not a lot less. My guess is that existing owners used to that level would generally prefer to have than in their Model 3.
