I've attached a link to a 180 degree rear view mirror that claims to eliminate blind spots from Hammacher Schlemmer. The site claims that this rear view mirror used by police officers and professional racecar drivers. The site also claims that it's easy to install as it clamps to your existing rear view mirror without requiring the use of tools or adhesives. I've ordered one but it hasn't come yet so I can't verify the ad's accuracy. Here is the link: http://www.hammacher.com/publish/74978.asp
