Almost every new car sold in the developed world has a display in the dashboard, but very few actually have a Heads-Up Display (HUD) projected in the driver's line of sight. It's mostly just premium models from GM and BMW that come with this feature. It's a shame that more cars don't have a HUD as it really does help to reduce driver distractions.
This is by far the best feature of our BMW F10 (manufactured in 2014 IIRC). I hate the distraction of constantly checking my speed in town, where there is a mix of dense traffic, many obstacles, outright stupid cyclists ignoring all traffic rules and aggressive motorcycles drivers and tons of radars that fine hard.
I've noticed with my previous car (also BMW, E46 that I will remember fondly for the rest of my life as amazing car but not due to this) that if I looked at speed, my peripheral sight of whats happening on the actual road was almost 0. I may notice break lights of car close to me if its newer car, or an atomic blast, but anything else simply no. Just something very bad waiting to happen.
Its such a great safety feature even with minimal info (current speed, current speed limit, and if car navigation is on some basic directions, but maybe thats the key, don't clutter it with too much info) that I would make it mandatory if I were EU and subsidize it.
