I tried, and failed, to crash a BMW i3 at CES 2015

During a demonstration of BMW's ActiveAssist technology in an i3 electric car, I aimed it at a fake brick wall and floored the accelerator, only to have the car hit the brakes.

LAS VEGAS -- On the top level of a parking garage during CES 2015, BMW invited me to take the wheel of its i3 electric car, modified with its experimental ActiveAssist technology. Through a narrow course of soft barriers I followed a BMW minder's instructions and purposefully steered into the obstacles.
