Bonus: The danger of using an air conditioner right after starting a car is overblown.
There was an online rumor that said if you left your car parked in shade (let alone in the sunlight on a hot day), when you entered the car and turned on the air conditioner, you'd breathe in a dangerous toxin called benzene. In order to avoid serious health issues (such as skin problems, liver, and kidney dysfunction), right after you start driving, according to the source of the rumor, you are supposed to open the windows in your car for a couple of minutes to ventilate the air. However, there is scientific proof that this is just an overblown concern. The American Chemical Society released a report that concluded there is no dangerous amount of benzene in parked cars.
