Regardless of whether or not there's an actual need for pedestrian warning systems for hybrid and electric vehicles, the U.S. Senate has voted unanimously to approve a measure that would make the noise-adding setup standard on all vehicles that can operate – even if just momentarily – without the burble of an engine.
Regardless of whether or not there's an actual need for the pedestrian warning systems that continue to pop up on hybrid and electric vehicles, the U.S. Senate has voted (unanimously) to approve a measure that would make the noise-adding setup standard on all vehicles that can operate, even if just momentarily, without the burble that emanates from a gasoline or diesel engine. The bliss of rolling down the road in an electric drive vehicle in near silence is now one step closer to becoming an un
