This would be awesome on the nose of my car

My most hated move in driving is having to pull out onto a busy street when there are cars parked and you can't see the cross traffic. If you had something like this on the front of your car, you could see both directions by just sticking the nose out.

If you had one on the tail of your car, backing up would be safer too.
