Do I need to call a taxi next time I have been awake for 18+ hours, is the AF going to pay for this after a long shift or flight? Because you can still get arrested if the cop thinks you are impaired. Even though its not illegal to be drowsy they can still charge you if they think you are impaired.
Is it safer to drive after being awake for 18 hours or have a beer and drive?
Point is this is not a black and white problem and we can not treat it as such. Yes drunk drivers are assholes, i've been hit by one and was lucky that I was not seriously hurt.
