That uphill performance looks impressive. How does it do going downhill? Every semi I've driven had a jake brake, compression brake, to help slow it on downhill mountain passes. Anyone that's driven 80,000 lbs down a 5-7% grade with fading brakes can tell you it can be a bit of a scary experience. I've had it happen. Jake wasn't working, going down a pass. My partner was driving. He had to keep the RPMs up in lower gears to save the brakes. Ended up blowing the motor. We were 80,000 and he managed to get us on the flat without using a runaway ramp or killing us. This was in Colorado on the downside, going into Steamboat Springs.

Fantastic! The electric motors act as generators while “braking” downhill.
Heck, I went downhill in a suburban and it was hairy enough- I can’t imagine driving it with 80,000 truck and load. Scary is an understatement lol.
Very good question but based on Tesla’s cars, regenerative braking is probably included.
A very true concern is REAL stopping power.
All Tesla’s run into brake over heating very quickly when pushed to the limit.
Changing to carbon ceramic fixes the problem but you then loose regenerative brakes.
