I would like to see the next generation of RD contain a "learned" discriminator feature. For example:
I drive 55 minutes into work each day. Along my route I know exactly the spots where my detector will false alarm because of "auto door openers", "hospitals" etc. The frequencies these false alarms occur are_the_same_each_day at the same spot.
Whats even better, I'm familiar with the frequencies/bands the local and state police use and NEVER on the same frequency as my "false alarm frequencies."
So while driving by my false alarm hot spots, I like to be able to hit a button that will discriminate against that one specific frequency and have it stored it into a user profile.
Now I'll be able to travel by these same false alarm hot spots without the RD going off and still be able to have detector set for high sensitivity.
Obviously disable this user set profile once I drive elsewhere.
