A comment on Tesla has applied for a patent for a new electromagnetic windshield-wiper system. Parent comment
* Only when it rains. (It's worthless the rest of the time)
* Only if all of the motor power is saved. (Presumably the new mechanism uses some power)
* Only if the motor is running at full power the entire time it rains (even on "high" this is not true).
* Only if range is not otherwise impacted by the rain (nope).
If it rains all the time, and the above are all true-- yes, it's worth 0.5%.
