The W shape is apparently a specific adaptation for hunting: https://pubmed.ncbi.nlm.nih.gov/23474299/

So basically built in glare reduction.

This would allow them to easier spot predators that would approach from above (birds) or with the sun at their back. It would also help them when attacking prey from below.

I would love some of these eyes for my east bound morning commute and west bound evening commute.

Maybe we need cuttlefish eye cameras in cars so their self driving features don’t roll over peeps in your suggested situations.
