Hmmm, is driving a car with a manual transmission (something the Amazing Race has actually had as a task) a mental or physical challenge?

Or refueling the car with the correct fuel (i.e. noticing the "DIESEL FUEL ONLY" label on the fuel door)?

I drive sticks (in fact I drove my first automatic car when I was around 28 years old).......then again at the exit of Edinburgh airport....I had a hard time figuring out how to engage the reverse (its the one where you have to push the stick inwards while shifting the gear)......I actually had to stop outside a security point and ask a very nice policeman ......"excuse me....I am not a total idiot BUT ........"
Second part.......PETROL ONLY (at this point 6 years of studying chemical engineering kick in ).....ok so petrol...petroleum.......both gas and diesel are part of the refined destilates from petroleum......is diesel ..petro?? ! crap! oh well......it says petrol at the gas pump....who knows wth this is........I will look it up in wikipedia later LOL
First trip to Europe had a few of those embassing-idiotic stories
