A lot depends on where you ride. In Kansas or Oklahoma, it probably doesn't make much difference, but here in Atlanta Georgia, or in any high volume traffic situation, it is extremely important. Of course many drivers these days don't see any reason to use their turn signals anyway. They are only interested in where they are headed and couldn't care less about anyone else. The terrible thing about being hit from the rear is that you're not likely to see it coming and even if you did, you probably couldn't do anything about it anyway, and that’s why its so important to clearly indicate any turns. When I'm going to make a turn, I want the idiot behind me to understand what I'm going to do, otherwise he may just fly around me a wipe me out as I proceed with my turn. There is just no good reason to 'hide' my intentions or make them so indiscernible that no one can hazard a guess. If you were to indicate a left turn by hand, for example, you extend you arm and hand to the left. The guy who came up with the Integrator would probably just point with his little finger while still holding on to the handlebar. Have you ever seen a policeman directing traffic using only his fingers with his arms folded? Sounds silly, but so is the integrator.
