Hmmm, maybe it's just marketing hype. The size of the last update was very nearly the same size as the previous update without the speed cams ... 230,912 bytes to 229,824 bytes.
It will be interesting to see who gets a speed trap alert first ... probably DJ if anyone.
Surely you would be able to. That is a feature I would only use on long trips but not in the city or for normal driving where I already know where the hot spots are from experience.
