Hivemapper has built a dashCam that you can install in your car to map the area while you drive. They have around 10,000 dashcams contributing to the global maps. Many are in orders and are waiting for their dashcam. They are shipping about 500 of these unites per week.

So far they seem to have progressed well and working with community feedback. Show Less
