Say NO to blindspots

Here is a neat trick I learned from the book Traffic to get rid of blindspots:

While sitting in the driver's seat, lean your head against the driver's side window. Now adjust your mirror so that the edge of your sight barely touches your car. Lean right so that your head is between the driver's seat and the passenger seat and do the same thing for the passenger side mirror.

When you sit back upright, the mirrors will probably be facing further out than you are used to, but it should show cars in the side mirrors that you can't see in the rear-view mirror. This is all assuming you actually use the mirrors...
