I've returned to this story to address the cynics and naysayers.

First of all, a pertinent question posed by many is how they knew it was petrol. The answer is in fact quite simple; the smell. When we got out of the car to speak to the pair, the stench of petrol was instantly detectable in the air and as soon as the Qatari kid mentioned it we realised he was right. They'd somehow smelt it in their car behind us. Furthermore, from the description given by one of them, it wasn't a few droplets or a trickle, but was gushing out of the car in copious amounts. The leak was not from the engine bay area, but from the rear of the car somewhere near the fuel tank, so I presume easily visible from behind.

Secondly, the fire extinguisher was indeed missing and i hadn't noticed before as it is a company car that i'd only recently received so had no need to verify its presence aforetime.

Lastly, I am not disputing the presence of other flashing road users and their possible ill intent, however my story is about the ones that flashed me last night. For me, these are typical Qatari youth.

Perhaps my glass is half full.
