I generally agree with this, but then, I would also take into consideration that driving at, say, 70MPH with a Camrys is not the same that doing it with a BMW.

All other things being equal, you are way less dangerous for others drivers in the latter case and this should also be used to "equalize" the fine for speeding. Or is this too unfair for the people that cannot afford a BMW ?
