Since it sounds like most or all AWD model 3's can be software unlocked to P performance, do you think Tesla will or should unlock the AWD cars to P so people can get away from hurricanes faster? After all, they unlock battery capacity and give free supercharging.
Tesla is a responsive company that listens to their customers to an almost unheard of degree.
If you can build a case that unlocking this will make a substantial increase in safety during an event or evacuation, I wouldn't be surprised if they gave it to you.
I don't think there is such a case to be made - if anything, the extra power on slick congested roads sounds like an increase in risk to me.
