I’ve been using Waze for a last couple of years and I am very thankful for all of the ideas and their implementations in your app. I would like to propose and additional feature to compliment people who drives with keeping the ecology in mind. You already collecting data about how fast people drive their vehicles. If you can build a profile for each Waze user about his/her eco-driving habits and then for instance collaborate with a financial institution that can offer a lower interest rate to those who are eco-drivers, or something like that I think we all are going to benefit from this. Most of all in global view we are going to use far less fossil fuels and thus we are going to effectively fight with the global warming. In a big fight every solder counts and if an average Joe can participate at no additional costs what so ever to the global battle for the greener and better Earth future, isn’t that a great goal to achieve? At the same time we can motivate people to become a “healthier” eco-drivers and they will benefit by receiving a social score, or a lower interest or something else.
