I've never heard of any specific name for it but basically it happens because you are panning so close the angle of the car changes a lot over the length of the shutter duration the only bit that changes the least is the bit that you are tracking as its in the center. It can be used to great effect, if you want to stop it and get the whole car sharp you basically have to use a higher shutter speed or else change so the car will remain at a more constant angle to you during the exposure.
