Oooooh. Doesn't seem like it'd be that hard to mod, does it? (I know, famous last words, right?!) Wonder if a relay could be installed, wiring the sensor cue to the front wipers back to the rear wiper... The detail to handle would be what if sensors are active and the rear wiper is activated by hand, the relay would have to be able to switch over to manual without causing any probs in the circuits. I'm up to my ears in other mods right now, but that seems like an interesting one, too! Anyone want to give it a shot?

In terms of the front wipers, I agree it's just the nature of a sensor. Making it too sensistive would be even more annoying. Mine are adequate at any given time, with the sole exception of light misting that obscures the windshield but doesn't trigger. Within 1 or 2 secs of thinking about manually upping the wipers, the sensor kicks in. No complaints here.
