I fly a lot, and have noticed a very strong smell of fuel several times on various aircraft, while still at the gate just before taxiing to the runway. It always baffles me that passengers don't overreact to it, because it can be very pungent and will cause a mild headache.

I've always wondered how toxic this is. Apparently it's caused by wind blowing jet fuel fumes into the air conditioning intake so it's indeed fumes that make it into the cabin for a few minutes.
