That happens to people talking on cell phones too. They're cruising along below the speed limit in the "express lane" and then suddenly realize they have less than 200 feet (60m) to their exit. They fly across lanes with reckless abandon. They got on the highway, were having a good conversation with someone, and suddenly they're already there!
Sometimes their teleporting powers are really strong, and they have to reverse down the highway (thankfully, I've only witnessed this occur on the shoulders).
edit:
Any accident occurring while the driver of the vehicle is using a cellphone should be treated as a DUI, if not worse, as it is much more easily preventable. It is a lot harder to convince the drunk to not drive in the first place, usually requires peer pressure.
