Be wary. 

You may be the best driver in the world, but you still need to worry about other drivers, including the woman who's putting on her lipstick at 70 miles per hour (113 kph). Put extra space between your car and the one in front of you to give other drivers enough room to make unexpected moves. Check your mirrors constantly and always try to look as far as you can down the road ahead. Always have an escape route you can use quickly if someone sneaks into your lane unexpectedly.
