Lotus introduces safe and sound hybrid
Here's a big problem with hybrids and electric vehicles: they don't make any noise. This can pose a safety concern for those around the car, who won't hear it pulling away from a light, backing out of a parking space, or cruising down a residential road. It's the driver's job to make sure they operate the vehicle safely, but the sound of a vehicle can act as a warning to pedestrians in certain situations.
