Why aren't blind spot mirrors as basic as windshield wipers or headlights on a car?

Question

It is a great help when driving. I think it would cut down on alot of careless driving. My friend was very shook up when she had a minor car accident. I promptly bought her blindspot mirrors and she has never put it on her car.

Answer 1

As with most things manufactured, auto makers put just enough safety equipment on cars to be legal.  

I don't depend on blind spot mirrors.  I adjust my mirrors to reflect more of the lanes of traffic behind and beside me.

Normally, a person adjusts the mirror so that a small amount of their own car is visible in the mirror.

Try moving the mirrors OUTWARD to show more of the roadway beside you.  This will take a bit of getting used to but it works very well.

Answer 2

we do need them

Answer 3

Cuz she thinks blindspot mirrors are uncool... and shes a fool.

Answer 4

These mirrors would make the vehicle cost more because they would the type that would be incorporated into the side mirror but no aftermarket product is a substitute for driver skill and know how.

Drivers must properly adjust their new blind spot mirror, and become accustomed to using it.
