Storm chaser Steven Green had this custom car built so that he could drive it directly into tornadoes -- which he did so in 2004. The chassis was originally from a desert racing vehicle which was converted by Green into its current incarnation at the price of half a million dollars. The Tornado Attack Vehicle, as it's called, is now covered with 16 gauge steel and the bulletproof windows can withstand a .38 bullet if necessary.
