Let's be realistic here: 10 to 60x per second. When was the last time you saw a wiper blade sweep 60 times in 1 second. Even a 1 sweep per second is long.
So there are at least two ways wipers can work. They can have a separate park function. These are annoying. In a FORD I owed way back when, turning off the switch would instantly reverse the direction without completing the sweep. In the FORD, the park logic was part of the wiper switch. One car the family owns makes the same length sweep, but with different start points. You also have low and high speeds to deal with.
"Generally" you can pulse the wiper switch and the wiper motor takes care of the rest. So, think of a 1 second pulse occurring at some rate from say 10 to 60 seconds using the low speed winding for intermittent. The design is not as simple as it seems.
