It must also include a large fine to make it remunerative to the police agencies.
No, a fine is NOT enough. Impound cars and prison. These people are worse than drunks. I would rather have a drunk coming at me than a text message driver.
At least the drunk might actually see you and try to move out of the way.
Had you read a little less quickly you might have noticed the word "also." The fine is necessary to induce the police to make the arrests and charges. They make some money out of it. If you insist that traffic enforcement be motivated only by righteous anger then you will be eternally disappointed, both in the lack of that indignation and the lack of enforcement.
