text: Challenge of Exploring Venus.             Cars, they help us get from point A to B in a shorter amount of time, but at what cost. Cars are a large source of stress, produce large ammounts of pollution, and seem, even now, to be going out of style. Cars are a luxury, not a necessity, and now they might not even be as usefull. More and more people are putting down the car keys and choosing instead to take a bike or bus. Cars are just too stressful to be a necesity.
