Longstanding one would be the power to pause time and rewind by 10 seconds to avoid alot of mistakes with a redo. Probably a old classic though.
More recently, the power to safely deflate all 4 tyres on a car just by staring at them when they drive up at me onto the pavement to park without just waiting a few moments, or when they accelerate towards the pedestrian crossing after it starts to change to red.
