Here is an article that outlines why many radar detectors or not much use and why ones that are, are very expensive.

I have used radar detectors since the late 70's but when my Valentine's remote audio module died a few years ago I just didn't bother with it anymore (after nearly 40 years of RD use). Several reasons for this:
- new car's onboard things mentioned in the article.
- newer, instant on, guns (if used as such) give you no time to react if you are targeted. Granted, they may give you a chance if someone in front of you is targeted.
- there are more and more "jammers" in use which no amount of RD tech will filter out.
- traffic on most freeways is moving much faster (on average) than yesteryear. Most interstates in the west are 80mph at least so you can cruise comfortably at 85-90 and not have to worry, which is fast enough for most of my riding there.
- I tend to ride mostly two lane secondary roads and find that I can ride slightly above the speed limit through corners and then, by not speeding up on the straightaways, I am relatively immune. (remember the article "The Pace"?).
- I try to NEVER speed through small towns since many of them use traffic violations as a revenue source.
- I try to be stay aware of what is going on in front of me. eg. seeing brake lights where there shouldn't be any, sudden decreases in speed limits for no legit reason, etc..
- I try to utilize a "rabbit" whenever possible.
Since I have given up using the RD, I get about the same number of tickets/year as when I use one. Anecdotal for sure, but for me, I cannot see spending the $600-1000 needed to get one of the new generation detectors......yet. As the traffic enforcement becomes more draconian, that may change.
