First, welcome to the addiction. Think you need to use some reverse parenting and have driving rights on the weekends.

Spot mirrors are good, but they are limited. The rear view camera is great for backing and parking, but here is a real jewel of a mirror. Understand it was designed by the police in Germany for the autobahn. Maybe that is why it is called the 'Autobahn Mirror'. Well worth the money and A.J., (username Totallto) thanks for turning me on to this mirror.
