what kind of mirrors are these?

The other day I was on GMC's YouTube channel and was looking at the 2018 Sierra videos. I noticed that they had different mirrors with a extended corner. Anyone have any input?

Never seen a mirror like that. Maybe those are cameras attached to the mirrors.

Looks like Echomaster add on.

Whatever they are it does not look like the occupants are too happy with them they have a non expressive look on their face...

Probably because they are not real people but actors.

They know how proud GM is of using real people in ads instead of non-real people. They are just trying to hold back their discontent ;-)

Thanks guys for the info. And I agree the look they have I would have it too after learning those camera's cost $900.
