Hey, all you interstate drivers! Just to let you know, a lot of you seem to be of the opinion that you can drive and talk on your cell phone at the same time, and while, yes, this is technically possible, your variable speed, your wandering across lanes, your unawares reaction to other drivers suggests what the rest of us already know, you can't! All day long today data points were collected, and every single one of you who committed the above mentioned offenses were gabbing on your phone! Of course, maybe you're just this bad at driving all the time. Start with something within your grasp, like chewing gum.
