DARPA, the governmental department that researches crazy things that may eventually make it into the military, is currently working on an “ultrasonic curtain”. In layman’s terms, it’s a sonic cloaking device designed to lower noise levels by at least 30db in military vehicles.
Seen in their prototype vehicle to the left, DARPA plans to give this technology to eccentric billionaires everywhere so they can escort their lady-friends back home in an emergency. Possibly even while running over civil emergency vehicles and driving on top of buildings, instead of around them.
