When I was in a high school driver’s education class, the instructor put traffic cones stored in the car’s trunk onto a parking lot and we, three students per car, would take turns practicing parking. I don’t know where you can get traffic cones.
I have a narrow garage so I have to be super careful when entering and exiting my garage. I’d like for my next car to have a feature called “four wheel steering” (4WS). Some of the 1990s Mitsubishi GT3000 models had this feature. There may be other car makes and models that have 4WS but I haven’t been keeping track. It makes a car more maneuverable to steer and especially in tight spaces.
The outside rear view mirror is a feature that I’d like to see go away for good. Because outside mirrors protrude from a car, they’re vulnerable to damage. Cameras can take the place of the outside mirrors. I think Japan allows cars to have this feature. It’s probably just a matter of time when U.S. cars will have 4WS. Most cars already have a back up camera with the monitor screen in the dash.
