Ah, whatever. A little bottle of Rain-X costs me $2.00, and lasts five years. With a fresh coat at highway speeds wipers are simply not needed. At slow speeds, you can run your wipers at a much slower rate (a wipe every five seconds instead of constantly) and so you save both your blades, and the wiper motors if you're worried about that.
A lot of times, in the rain I notice people driving really slow, wipers running like mad... they are driving slow because they can't see! Meanwhile I can see just fine. If I were king-for-a-day, I'd make Rain-X mandatory. If I were an insurance guy, I'd hand out free bottles from my office.
