Sorry, Bat fans, but the caped crusader has been roundly denounced by science as about as useful as a fart in a jacuzzi.
Compared to the other heroes on the list, Batman's positives (of which there are few) definitely do not outweigh his drawbacks. One of the major issues that students David Marshall, Tom Hands, Ian Griffiths, Gareth Douglas take with The Bat, is that his mode of travel - gliding about the city with his batcape - would more than likely turn him into a pile of Bat Jam on landing.
The students ran the numbers and found that, using the batcape, Brucie would be travelling at speeds of up to 110 km/hr which, in the absence of a bat-parachute, would be like getting hit by a truck.
When you factor in the reality that Batman, whilst armed to the teeth with gadgets and rippling biceps, has no real powers to speak of, particularly ones that might protect his squishy mortal body from the trauma of violent vigilantism. Not to mention the fact that he has so far not managed to bring Gotham's crime under control in over a decade of beating up street level crims whilst breathing through his mouth, despite it being his sole raison d'etre.
Science has it, Batman is lame.
