Since I'm driving around Jacksonville a lot more recently, I have noticed something that makes me kind of ill. At least once per day, I get behind a vehicle that smells of gasoline, and I kind of wonder why. The smell isn't coming exclusively from old pickup trucks, though old pickups almost always smell like something is wrong with them. (I tell my kids that an old Dodge smells like gas, an old Ford smells like oil, and an old Chevy smells like gas and oil.) In Jacksonville, it seems that decade-old compact cars, newish SUVs, pickups, delivery vans, motorcycles, and everything in between, often emit a gassy smell.
