I know that the topic of bicycles, carpool lanes, and busses have been brought up in the past, but I just had another idea to add to the list.
We all know that a person on a bike, in a carpool lane, as well as people riding busses can throw off the traffic readings for the main line during traffic. But!, what if there was a commuter button to toggle whenever you enter a carpool lane. This would negate the traffic readings. However, here is the twist! Since everyone wants to go green these days, have waze record separate green points for traveling green. Since there are those that like to have the highest points in everything, why not put that to good use and try to get people to top the green list.
