 Uber is out with a new initiative to cut down on congestion in some major cities. Uber is planning to give $1,000 to people who volunteer to give up their cars for five weeks. The money is intended to be used for rideshares, but also public transit, car rental, and scooter and bike share programs. Uber says it's intended to highlight the high cost of car ownership and the effect that cars can have on public health and the environment in urban areas.
