Comment I'm fine with this, with a few caveats (Score 1) 496
Pros:
Almost nobody adjusts their mirrors correctly, and they almost always leave big blind spots.
The cameras can offer perfect placement for blindspot visibility.
On motorcycles they can be next to useless (my elbows look great, thanks for asking)
It will probably be coupled with a collision warning / lane departure system.
Neutrals:
You know they are going to make them record video which can be recovered in the event of a crash.
Cons:
It better be high def.
It better offer enhanced (contrast improvement) night mode (IR capable) in a non night-vision ruining way (Red & black at night)
It better offer some way to judge distance.
The screens better be glare proof.
The lens better keep itself clean.
