He put 99 smart phones in a wagon with all of them running Google maps in drive mode. Google interpreted this as a traffic jam, and made other cars avoid the area.
Rich enclaves paying you to drive a bucket of cell phones around the neighborhood slowly in an electric golf cart.

I feel like there's a great movie plot point you could write where the bank robbers use this trick to clear traffic out of their way during the escape.
During the solar eclipse of 2017, I drove to a small town in eastern Nebraska. The town had a 10k race that day. There were about 3 cars, including mine, on this stretch of road. Stop-and-going inbetween the runners. While my wife drove, I watched Google Maps. It accurately put a short red line on our part of the road. Amused me though that it only took 3 cars to accomplish that.
Hah! I have a 2017 eclipse story related to this, too!
A few days after the eclipse, we were driving through Custer State Park in South Dakota. There were relatively few cars on the road but Google Maps would inexplicably show these very short red traffic jams.
We quickly realized that we could anticipate upcoming bison sightings as people slowed down to take pictures of them walking (or sleeping) on the side of the road.
