So many things to consider.
" ... Navdy has refuted claims that its new device is dangerous, ..."
Have they refuted these claims or have they just denied them? Refutation needs proof.
"You hear that? Pilots use it; it's safe"
Pilots have lots and lots of training. They don't have other aircraft jumping out in front of them or traffic lights turning red suddenly as they fly along.
"Projected like it's two metres in front of you, so you never have to adjust your focus away from your driving."
If you drive around focussed on what's two metres in front of you, you'll miss everything you need to be paying attention to.
