This reviewer got a lot of things wrong about AP and FSDC (he did not qualify his statements by describing what the car can do now vs. what Tesla says it will be able to do in the future, he conflated the two) but overall his comments were mostly accurate. How he got a 4.4 sec 0-60 time on Vbox (twice) I don’t know, but that’s what he got.
4.4? Perhaps because he wasn't necessarily on level ground?
