That stopped the shmearing. We haven't had a strong enough rain to criticize the speed. The wipper do seem slower than the prior 650. However the older models had a cam that shifted and accelerated the wiper as it moved across the windshield. That could be a difference which would affect a perception of speed.
I'm sure the mechanisms are different on the E series and F series cars but I don't think it's perception. My wife currently drives an E71/X6 (which I always drive when we're together) and the wiper speed (highest setting) on those blow my 650's away. I think they just screwed the pooch on this one.

If it wasn't a lease and I was going to keep it for a few more years, I would look into retrofitting the wiper motors from the E series. I'm not gonna lie, I get a little uncomfortable in anything heavier than normal rainfall. It's that sucky. Never before, in my life...
