This is similar to my "Paces to Pennies" app idea, but this is dedicated to the drivers more than the walkers. However, those who have a car can apply for both "Pedals to Pennies" and "Paces to Pennies" since you become a walker once you're out of your vehicle. Anyways, the reason of how an app can help innovate driving and traffic can be by people having a more fluent psychological mindset in terms of "if I want to earn more, then I should do/act better".
