Being Inside a Car Can be Worse Than Being Outside
While it may seem like being inside a car could offer some protection against air pollution, that isn’t always the case. Often, motorists are exposed to nearly eight times as much pollution as a person on a bicycle nearby.
Usually, vehicles are directly in the path of exhaust fumes. If you have your car vents open, that polluted air makes its way inside. Then, it can become trapped in the vehicle.
If you are sitting in traffic, using the recycled-air setting in your car can help. It limits the amount of fumes that come inside.
