What Happens: Along with his usual rucksack of improbable technological goodies, 007 is also handed an Aston Martin Vanquish which comes with a cloaking device as standard.

Why It's Stupid:  Yes, that’s ‘cloaking device' - like a hip-hop Klingon might use to pimp out his ride. Honestly, WTF? Bond-tech works because it’s not only possible but just on the edge of probable. This one is clearly in the realm of distant sci-fi and – unless you’re cool with waiting for the battery to run flat before you find where you parked the thing – really impractical.
