Blind Spot Mirrors

Was probably posted above, but there is no such thing as a blind spot. Only improperly adjusted mirrors. http://www.caranddriver.com/features/how-to-adjust-your-mirrors-to-avoid-blind-spots

 

Well technicaly speaking there are always blind spots but you can make them very small by having properly adjusted mirrors. If done right you should never have a vechile fully hidden in one I'd argue that you could still possibly miss a motorcycle at certain points or fail to see it even when its in the mirror just barely. Of course that leads back to having a good scan and doing a proper lane change.

They should have shown the FOV cones so you'd see how huge they blind area is with bad adjustment and how small it is with good adjustment.

Here is a better description you have to scroll down a bit the topic is about multiple screen setups and he uses mirrors fov to make his point

Do an experiment tomorrow. When you are behind people in traffic see how often you can see the driver in all three mirrors. The number of morons is staggering.

 

You've greatly overstated that. There are in fact blind spots on many vehicles even when using the mirror adjustment advice you linked. The advice in the C&D article linked reduces overlap and expands field of view but can add small close in blind spots on many vehicles - especially SUVs and trucks with windowless shells. If you are properly monitoring your mirrors at all times naturally you should notice someone entering this close in blind spots - but even so it still demands a shoulder check or a convex mirror for proper coverage.

So yes, many people have way too narrow a field of view and way too much overlap and the C&D article can help that. But in most vehicles you still should be doing a shoulder check. And because of the idiotic US rules you also need to be very careful on the drivers side since it is mandated all US sold vehicles must have flat (i.e. not convex) mirrors on the drivers side. That leaves you a choice of blind spot location on most vehicles rather than the ability to completely eliminate them on the drivers side. Unless of course you add a convex mirror - as this thread is about.

 

If you need to see in a "blind spot" alongside the vehicle move an ear closer to the shoulder.
