Imagine you could win the lottery just by driving safely.

The intriguing concept is simple: All fines exacted from speeding drivers are put in a pot to be paid out to one law-abiding driver selected in a "lottery."

Here's how it works: A speed camera takes pictures of all drivers' license plates. Speeders are fined while the safe drivers' plates are compiled in a database and a lucky law-abider is then selected to receive the total amount of the speeding fines.

Effectively, all drivers are "in it to win it."

That's the idea that blossomed into reality for its originator, Kevin Richardson, of San Francisco, who won a VW-sponsored competition earlier this year and saw his innovative theory played out on the streets of Stockholm, Sweden.

"You can't stop people from speeding," he said. "The real point is it makes you aware of your speed. Being aware of the law versus safety, it's more fun, like a game focused on the driver and less on police."
