These vehicles are capable of doing so - they simply have a limiter on them. It's like saying an NVidia card can't mine cryptocurrency because they added a limiter in their drivers or something. Or that a truck with a governor on it could not go faster than that with the governor removed and no functional changes to power output.
Even so, I can go at least 4MPH greater than OP's suggested maximum speed legally.
Okay, you should have said that in the first post. If you're not using the class of vehicle the comment was talking about, your experience isn't really relevant.
