On the other hand even a 1 mile (probably less) saving over a 5 hour (~200-250mi) trip through the rain might as well be a rounding error regardless of the fuel used. Many other methods for achieving the same saving are not as flashy though.
I imagine the most important way is to ensure optimal tire pressure at all times. Many people tend to ignore this even when having pressure sensors at hand which leads to a whole lot of wasted fuel.
The reason wipers only received minor optimizations over the decades is because they work well, are cheap and enviably reliable. So any new wiper system design has a high bar to pass, beyond using new tech.
