The document discusses defensive driving techniques, specifically the proper positioning of side view mirrors. It notes that over 600,000 lane change accidents occur annually in the US, with blind spots from side mirrors being a leading cause. The author recommends setting side mirrors at a 90 degree angle rather than the normal position, which significantly reduces blind spots and allows drivers to see other vehicles faster and for longer periods of time. This positioning has numerous safety benefits over traditional mirror placement and can help avoid accidents by improving visibility. Drivers are encouraged to adjust their mirrors to this technique for better safety and comfort.
