Waze, is an Israel-based social navigation and traffic service application that allows drivers to share traffic information at realtime. Its interesting to meet other Waze drivers on the street and to share driving experiences. When i tested Waze today, i came into a bad hailstorm which i immediately reported to Waze. During my trip i could see a lot of different traffic messages from uther drivers near me.
Today Waze announced that their user/driver base has reached 20 million active users and they are growing really quickly, as they gathered half of them in the last 6 months.
