I was just trying to make an impression lol. Anyway, if you have your window open next to a F150 or <I waste more gas than normal> car, you will smell gas, oil, whatever the hell it is. When you're biking, the wind is smacking against your face and it just feels more "fresh" or whatever, sure when you stop, you'll smell some of the crap from cars, but it's still better.
Edit: I think you're trying to take it too literally.
