Awesome and once you get the "boat mode" OTA update, you can motor over to Maui.

We drove Mauna Kea this summer just before dawn. Great test of regenerative brakes! Go CT.Aloha!
Enjoying my new FS AW Cybertruck on the Big Island of Hawaii!!
I finally got a chance to take it on some of my favorite off-road adventures this week.
Bottom line:
The truck did great!! The regen controlled the descent on Waipio valley road and Mauna Kea road....no need for brakes. Brake temp at bottom of Mauna Kea (at visitor center) was 55 degrees F. The ranger said it was the lowest he had ever seen. Very comfortable ride compared to my 2018 4Runner for the same excursions.
The Excursions:
Waipio Valley - Drove down the "steepest paved road in the United States" using the trail assist at 5mph. It is a very narrow, one lane road and I did not need the brakes except to allow one truck to pass me going UP while I was going DOWN.
Used Wade mode to go thru the river (only about a foot of flowing water depth)
Mauna Kea Summit (13,796 ft elevation)
I drove to the Summit of Mauna Kea to watch the sunrise. I usually drive up for sunsets but this was my first opportunity for a sunrise.
It is recommended to "acclimate to altitude" for one hour at 10,000ft to avoid altitude sickness, prior to ascending.
I got to the top about 10 minutes before sunrise. Weather: temp was 38 degrees F wind 20-30 MPH.
Tried to get some "beauty shots" of the truck with the sunrise and observatories. (see photos)
Heated seats were used on the ride back down and never needed to use the brakes
Overall, it was a pretty awesome experience!!
Mahalo Tesla for creating the Cybertruck and making these excursions so safe and comfortable.
P.S. Both of these trips require regular 4X4s to use 4 wheel low and engine braking to control downhill descent to avoid "burning up their brakes". The ranger said that one driver told him that they did not use the brakes when descending Mauna Kea....he said "the thermometer doesn't lie".....the temp was 600 degree F and the driver was told to pull over to let the brakes cool prior to descending the final 4,000 ft in elevation to the Saddle Road. All detailed info is on TeslaFi.... which is such geeky fun to review.

Are guys still charging to ride people to the beach? I bet you could make some good money doing that, but the regular drivers might get pissed if you take all the businessI'm planning to go to the green sand beach at South Point. I made it once with my 4Runner so I suspect this will be fine!
What vehicle did you take up? My friends are asking if they can take their Model X or Ys to the top and I didn't know the answer. Mahalo!We drove Mauna Kea this summer just before dawn. Great test of regenerative brakes! Go CT.
We took a jeep rental. Charged up at speed on dirt portion with no problem. As a an X driver in the recent past I would go slow up and down If they allow that vehicle. It is 4 wheel drive.What vehicle did you take up? My friends are asking if they can take their Model X or Ys to the top and I didn't know the answer. Mahalo!

Please post your pics from your 4x4 experience on the way to green sand beach! I had one reserved, but it got too expensive, you're my only hope until the prices come down.I'm planning to go to the green sand beach at South Point. I made it once with my 4Runner so I suspect this will be fine!
