Early alerts would be priority and would spend more if the others only give you a second.
Front and back directional alerts would be nice but not necessary.
If there's one that's good but pricey, suggest it. Thanks.
This will be used on the PA/NJ turnpike. Do they use laser here?
One area says "speed enforced by aircraft". How does that work?
I'd figure it'll just give too much of a sense of security and Bam! ticket you would normally not get.
