Whatever sonic energy is transmitted through the car itselfwhile moving

is being contained/reflected/emitted by the hard top. The top itself might have more resonant energy in the frequencies the spl is reading, too. With the car moving, acoustic energy from the tires might be diffracting around the body and passing through the more sonically transparent soft top.
