That´s a really good advice! A friend of mine managed to hit a lantern pole while riding his bike and keeping his sight on a nicely shaped female behind. It took only 6 stitches to repair the damage. I admit that we did not act like good friends when we laughed at him for the mishap later.

Keep in mind that distance to the vehicle in front of you means time to react and safety. It might make the difference between a car crash and an easy stop. 1 second of driving at your current speed should be minimum. Less might work IF you had the reflexes of a fighter pilot. But why take a chance on that?
Situational awareness is important. So keep your mind on the driving and both hands on the wheel. Keep your actions predictable for other drivers. That might help you to stay unharmed.
Laws of physics are not legal stuff. They are applied without mercy and there is no appeal. Lack of experience does not earn you extra points.
Driving differs sharply from driving simulations. "Game over" means "Game over". There will be no "Start from last saved". The damage model is not pretty real it is real.
Too much speed is a cause for accidents. Too much speed does not always mean exceeding the speed limit. Low vision, low traction and children near the road might demand a substantial decrease in driving speed.
Always have the guts to be a coward. You will not win a medal for bravery in daily traffic.
Save driving and lots of fun with it.
