Personally, it bugs me! I like the windshield to be clear of drops even when I am not moving.
If you don't like it, you can just switch it into a manual setting.

The reason for this post is not to comment on wipers that work, but instead to see if there is an inherent design issue with the rain-sensing mechanism in these brand new US models.
(And I definitely will *not* be switching to manual to avoid something that's broken on my less-than-four-month-old vehicle).
There are two other respondants who indicate that they have seen this behaviour (although it doesn't seem to bother them).
My car has a problem at least 50% of the time. Even if Daimler-Mercedes indicates that the odd reset-like pattern is normal, the car still has a problem because it exhibits this pattern only half of the time.
If anyone else encounters the following sequence in your wipers, please consider notifying your dealer. Since they are new to these models also, the mechanics hold teleconferences to discuss these types of issues amongst themselves. If we all decide to just live with the problem, they'll never even be aware of it.
Here is the pattern that you might see:
About 50% - 75% of the time my wipers behave erratically when they are on auto.
Specifically they go through a wipe pattern that seems very much like a reset algorithm:
One slow wipe
Three fast wipes
Three decreasingly slow wipes
<pause>
One slow wipe
<repeat sequence>
