As I sat in traffic court last week for a non-moving violation, many of the cases were clearly he said/she said issues.. particularly with stop sign violations. I can easily see how this specific problem could be a source of abuse by both police and citizens.
Case in point - I stop at all stop signs. I usually count to 2 before moving, but because of the location of the white line, It may look like I never really stopped to someone coming along the cross street.
Are there any court-admissible devices that will accurately (and affordably) record vehicle movement, location, and perhaps speed?
