What would we do without wedges? We wouldn't be able to split firewood so easily and doors would be slamming all the time. But in some cases, the wedge isn't so great; like when a wedge-shaped car crashes into the back of the car in front of it.
A redditor caught this recently crashed Acura NSX outside the office window yesterday morning. From the look of things, the beautiful Japanese sports car was in the wrong place at the wrong time, sandwiched between the wrong cars. The low, wedge-shaped nose of the NSX plowed beneath the high rear of a Subaru Impreza Outback Sport, driven by a blunt-shaped minivan.
