Why it ran this way

The back road to Bryce: UT-24 past Loa, UT-62, then John's Valley Road (UT-22) through Antimony, confirmed by the instruments (day peak 8,385 ft on the dash vs 8,376 ft sampled along this road; the 9,636 ft Boulder Mountain crossing would have read a thousand higher). Left the Torrey 50A at 74% with no DCFC in town, ran 106.0 mi at 1.11 mi/kWh in a 16 to 23 mph west crosswind gusting 32, and rolled into Ruby's Inn at 1% state of charge, the closest-run arrival of the trip. 2h54m moving at 37 mph.
