writes "Just the other day we read about how the Department of Transportation will require all manufacturers to include rearview cameras on all new cars produced after May 1, 2018. But there's something else auto manufacturers are pushing for, the ability to replace sideview mirrors with cameras in 2018. Tesla in particular is pushing for this to happen as traditional mirrors are bulky, and not very aerodynamic. That lump of plastic can cause surprising amounts of drag on an otherwise smooth car body. Camera units are much smaller and can be made streamlined, or even mounted nearly flush with the body, thus reducing aerodynamic drag. The idea has been around since the 1990s, and many concept cars have used cameras instead of sideview mirrors for years. But how will NHTSA respond? Is it finally time to ditch the sideview mirror?"
