I saw some moron toss a cigarette on the ground before getting out of their car to fuel up last friday.
I did something semi-stupid myself a few weeks ago. I pulled into a gas station and checked my oil. The oil being low, I decided to add more. It was extremely windy out and I was attempting to do a 'long pour' without a funnel. Wind blew oil on exhaust manifold, engine compartment was on fire.
Want to feel stupid? Start your car on fire then run around in a panic looking for something to put it out. I felt like the 'FFFFFFFFFuuuuuufffffuuuuuu' 4chan graffic.
I was eventually able to blow it out with the help of the wind. No damage to car or driver was evident.
