I drove home by myself from Moab UT via Blanding, Flagstaff, Kingman, Barstow, Tejon Ranch to Fresno. I left at 7:15 MDT in Utah and arrived home at 3:00 AM PDT. I had to range charge in Blanding and Kingman in order to reach the next SCs in 2014--Needles was not built. I was brand new to Tesla driving so kept my speed on the longer legs to 10 under to ensure reaching the next SC safely.
Today, with Needles and Mojave, there would be no need to range charge at Kingman, and no need to detour to Tejon Ranch in order to reach Fresno. That, combined with a better understanding of range and speed, if I were to repeat that journey today I would guess that I could save over two hours on that route.
