I heard a similar story from a coworker. They were interfacing with a car via CAN. They had an engineer from the manufacturer telling them the details of the message they should be sending to demand a certain speed. Turns out the description wasn’t quite right. The message ID was correct, but not the endianness of the speed demand signal.
Thus when they tried to test it they thought they requested a stately 5m/s, but the vehicle thought they were asking it to exceed the speed of sound. Which of course it wasn’t designed to be able to do, but it still tried.
That’s why i prefer to have nice hardware e-stops on prototype vehicles.
