Do you often trip when you walk because you are always looking backwards? Have you lost good friends because you daydream of the past when they are talking to you?
Have you noticed that you can not look two ways at once, nor listen to two things at once, nor think of two things at once? You know what happens when you try to? You get driven nuts and don't look too good when you've rammed into something (figuratively speaking). You can tell the officer or the insurance person how important it was that you needed to look out the back window, while driving forward, but the piper will still have to be paid.
