Yes it’s something car manufacturers haven’t thought about in many cases....
My current Skoda is ok on both - I am waiting for delivery of the new one with the “virtual cockpit” (LCD display in place of dials and everything else behind steering wheel) and am already wondering if they have thought about polarised sunglasses on the new one. Never sure if the current one was just good luck or actually planned
You can see the effect with some screens outside the house and car too. Some used at train stations for example. In Sydney I noticed most were invisible until I tilted my head - but rather randomly some were fine.........
It really depends as to how much you have to rely on it. I find that the standard dial location is just fine. The occasional glimpse at Satnav instructions in-between the dials does the trick as well.
But if you are one of those drivers who put their phone/mobile Satnav device right in their line of sight you may like this.
An unobtrusive HUD implemented well can be useful, but personally I wouldn't spent extra cash on one. Especially not at the non-windscreen 'fake' hud that the mini does.
Whenever I’ve bought sunglasses in Spec Savers they’ve always told me not to buy polarised as you can’t drive in them (and this wasnt a HUD specific thing) so the moral of the story is, should have gone to Spec Savers. Sorry, couldn’t resist .
