Driving a rental? Borrowing your mum's car? All that matters is that you need to refuel now? And life would be a hell a lot easier if you just knew which side of the car the fuel cap is on. But wait, you do know!
See that little arrow beside the fuel pump icon - yep that's an arrow indicating which side to put fuel on.
That's it, no frills. And if you didn't know about this then join the club!
