A survey by Lego has revealed that more kids dream of driving a tractor, a train or a 4×4 than a supercar…or the Batmobile. The poll of 1,300 kids aged three to ten years old, on Legoland’s Facebook page, showed that 28% wanted to drive a tractor or a train more than anything else, while just 6% chose a supercar – the same percentage that chose the Batmobile.According to these results, being a bus driver is almost twice as cool as being Batman, with 11% saying they’d most like to drive a double decker.
