This morning on Where We Live.
I always thought the passenger side mirror was developed due to Saabs (joke). Because back in the day (late 70s / early 80s) it seemed like if someone came screaming up and passed in the right lane, s/he was driving a Saab. Or sat on your bumper and flashed the headlights if one was not doing 20 mph over the limit. I've never quite shaken the stereotype of the Saab driver as being a bit of a speed demon / hothead, although certainly other cars have filled that wanna-be race car driver niche in ensuing years.
