Not comparable. This is fueling tons of cryogenic propellant using systems which haven't been used many times end to end. Hydrogen in cars is compressed gas, and operations happen at a much higher frequency. A lot easier to work out the kinks before going for the real deal (rocket launch vs consumer car refueling). No comment on hydrogen as a car fuel overall, but compressed hydrogen and liquid hydrogen have completely different in handling requirements.
