Proof that it is hard to see out of the back window

[Cedar Butte]

I was at stop sign and a truck was cut the corner tight. I looked in both side mirrors and the rearview mirror and nothing put it in reverse and crunch.

I put a 6x8 3M stick on prism in the upper corner of the wiper area. Not as high tech as a camera but it works.

The dog thinks it’s cool to he looks through it allot when we are going down the road..
