I recently thought that this would be a few really nice features to have.
First off a Control Module that You could adjust the volume, adjust settings, etc.
The Main Feature, have a switch that instead of turning the jammer all the way off you turn the jamming part of it off which enables you to see if he's still shooting at you and how long he's shooting at you.
I feel that it would make users less prone to JTG LEO's
And If you state it in your manual to do this (Turn the jamming capabilities off when you coast to the Speed limit) then I think it could really help us out.
Maybe even incorporate in the Control module some new features
Incorporate GPS too
