The Mountain View police department pulled over one of the company's automated vehicles for moving too slowly, according to Zandr Milewski, who posted a picture of the incident on Facebook:

"We talked to the driver, apparently MVPD doesn't get NEVs [Neighborhood Electric Vehicles] and pulled them over to ask why they were all going so slow," Milewski writes in the comments of the post, which we spotted on Fusion.

Google confirmed the report with its own post on Google+ as did the Mountain View police department on its blog. 

"Driving too slowly? Bet humans don't get pulled over for that too often," Google quipped.

MVPD writes that one of its officers noticed traffic backing up behind a slow-moving car that was going 24 mph in a 35 mph zone.
