How will Google know if someone who is transmitting traffic speed information is moving in their car or simply walking down the street or sitting at a restaurant?
In other words, can a bunch of people who have the traffic speed transmission option turned on, but not actually driving, cause Google to think traffic is really slow in that area? |
