It might be costco or some other discount gas club

Taking the EPA estimate on an F-150 when there’s headwind and driving 75mph or driving in slush is very optimistic. 18 mpg makes the costs roughly equivalent at $2.87. I’ve seem mostly 18-20 mpg

32A at 240V is plenty of power. You will gain roughly 40-50 km of range per hour of charging.

If you ever plan on charging at other places without a charger (friends/relatives/work/campsites/etc) then a portable charger could be useful.

As others have said:

• Make sure the portable charger can handle that amount of power. If you end up charging at 10A, then you will be getting ~14km of range per hour of charging. This can still work, but is less ideal since your vehicle will need 10+ hours of plug-in time per night.
• Wear on a plug/socket can matter. Also, doing this inside of a garage is less risky than outside exposed to elements.

I remember something from the early Roadster development days where they were able to lock up the tires on dry pavement just with strong enough regen.

The point is that it’s easy enough to stop the tire from spinning, but traction control (and quality of tires) is what matters the most in stopping the car.
