We can an agree traffic sucks. It adds to air pollution, ruins relationships, waste time, hurts business productivity, and causes unnecessary suffering for millions. We also can agree that most of the traffic is caused by accidents. Here are a few solutions that might help alleviate this problem.
(1) A manufacturer that develops a technology that has been proven to prevent accidents (some already exist) and enable that technology to be installed on older as well as new cars at a reasonable price will not pay taxes on the profits received from such a technology.
(2) A company will pay no taxes on a device(s) that has been proven to enables traffic to move more effectively after an accident or allows a way for accidents to be cleaned up quicker. The company must insure that these devices are available to all safety officials at a price they can afford to receive such benefit noted above.
