This is just a perfect example of the fact that some people shouldn't drive. Irregardless of what they were doing in thier vehicle, they weren't driving! They are basically careless, reckless idiots.
How many of us have, while driving done a secondary thing? Lit a cig, took a drink, picked up an item to hand to a passenger, checked on a child or pet. Glanced at a map or GPS. Picked your nose or scratched your groin???????
They can't consintrate well enough to drive safely!!
Anyone (in your wayward youth) drink, smoke, toke, grope a date and drive at the same time----with out killing yourself or anyone else??? I think alot of people today just shouldn't be on the road PERIOD.
