Yesterday in a parking lot I witnessed a guy backing out with his face buried in his cellphone (still facing forward). So basically he backed up without looking or even glancing at his mirror.
I don't think so. His face was fixated on his cell phone while he idled backwards for a bit. Then he finally looked out the back window and finished backing up, then pulled forward.
I was being sarcastic. You must be truly disciplined to not use your phone while driving. I am not, good thing I do not have a functioning phone 98% of the time.
