With modern driver assistance packages, that's not true anymore. For example Mazda's safety technology apparently gives drivers access to radars and radar coverage that Tesla simply don't have; see e.g. http://www.mazda.com/en/innovation/technology/safety/active_safety/bsm/ http://www.mazda.com/en/innovation/technology/safety/active_... There's also been talk of mandating active safety systems on new cars because regulators are worried about the safety of drivers relying on just their own two eyes.
