On: A Tesla Semi has already traveled 250k miles in 1.5 years

They said “at” which specifies that they were carrying the maximum allowable load/it was fully loaded.

Tesla also said the cybertruck can win a 1/4 mile drag race that turned out to be a 1/8 mile drag race and even dubious at that.

I think the question is, at say 80k lbs max weight, how much of that was payload and how much was vehicle?
