As for lengths we've gone to find Superchargers, we've driven over 100 miles into non-Supercharger territory on multiple occasions to scout out possible Supercharger sites. That's how we found the Brush, CO Supercharger back in 2016. Those trips were in an S90D. Now with an S100D, I figure we could go at nearly 150 miles into uncharted territory when scouting for Supercharger sites.
