If you knew how wiper motors work then you'd know that would involve a lot of complex circuitry in order to get the motor to run slower, i think you'll find it may run slower on the downward stroke because the wiper blades cause drag as the car is moving forwards.
I don't give a toss how wiper motors work, or how you think they work. The fact of the matter is that, on my car, when you wash-wipe, the final downstroke is much slower than all the previous sweeps. Not all of them, just the final downstroke. This is not up for debate, it's a fact.
You're the one spouting the #####. During normal operation, the wipers come to rest at a specific point after each sweep. When they're switched off however (or are on auto and haven't swept for a while due to lack of rain) they park themselves at a position lower than the normal operational rest position. This position varies each time they park. This is easily seen by pressing the stalk down to provoke a single sweep, they will park in a slightly different position on each successive operation.Yet again, total #####!
This is another thing that would cost a significant amount of extra money and electronics to acheive. The wiper motor just goes round and round, it doesn't know where the wipers are in relation to the windscreen, thats done by the linkage. and i think you'll find IF what you say was the truth, then the wipers would have to stop on the upward stroke in a different position everytime to eliminate wear there too... keep taking the medication.
