using a RD is just one part of being a fast and safe driver. IMO people depend on their detectors FAR too much ! When I was regularly driving over the limit I soon learned NO DETECTOR will keep you safe without proper driving techniques to go along with it.
I will post just a few here I learned and others can add more.
1.) when cresting a hill or going around a blind curve ALWAYS LET UP ON THE GAS
I don't care if you have the best detector on the planet it will not help you. Police just love to hit you with I/O in these instances.
2.) when your driving in a open area and you see a car coming toward you in the distance LET OFF THE GAS
many a time this can be a unmarked car waiting till get right on top of you to I/O you.
3.) when you see a vehicle approaching you from behind and catching up to you on a country road let up on the gas till your 100 % sure it isn't a police car !
4.) always drive with your eyes looking FAR down the road.
You don't know how many times this has saved me !
