Regarding HUDs... it's the one feature I desperately want for my next car. I've been looking into aftermarket options, but all of them are ridiculously cheap and bad or vaporware.
I purchased a new C8 to add to the collection until my granddaughter is old enough to drive. The HUD is very, very good. I'm not sure how they managed on such a sharp windshield, but it's crisp and clear even in the brightest of conditions.
With them making so many things mandatory these days, I'd not be surprised to see them making HUD mandatory. It absolutely is easier and faster to read then just looking down. It may only be measured in milliseconds, but it's definitely faster.
