This poor Porsche learned that the hard way.
We've all mixed up what gear we were in or the gas and brake pedal. No one is perfect, but very rarely do those mistakes lead to an accident like this. This dash cam footage shows a Porsche driver in a Singapore parking garage reversing full-bore into another car. It's not known what caused the accident. Did he mistake the gas pedal for the brake? Was he driving a stick and giving the car too much gas? Either way this rear-engined beauty could be facing some serious repair bills. We can't tell from the video but the driver doesn't appear to be seriously hurt.
That's perhaps the only silver lining in this entire situation. Remember that next time you mix up your pedals and gears it could always be worse.
