Most guys who have seen any of the Batman movies would like to have their own Batmobile. There’s been several versions of it over the years, and just about any of them would be great to own.
A Swedish man created a do-it-yourself (DIY) Batmobile. He started with a 1973 Lincoln Continental chassis, and added voice recognition tech, rear-view cameras, satellite navigation, and of course machine guns. The engine puts out 700 horsepower. He also included a DVD player and a plasma TV, for when you’re taking a break from saving the world. (But how many cupholders does it have?)
Unfortunately, the cost is prohibitive to me ever owning one. It cost $1 million and took 20,000 man-hours to build.
If you want the newer Batmobile (the Tumbler version), there are actual ones that were built for the movies, albeit several different versions. But they are able to accelerate from 0 to 60 in 5 seconds, and they can make and land 30 foot jumps without tearing up. And there’s a version that shoots fire out the back. One of those would come in handy…
On a related note, there are several interesting articles at this link discussing The Physics of Batman. Well, they’re interesting if you enjoy discussing whether some of Batman’s technology is possible in real-life.
