Oh my SIL had one of those for a while, it looked pretty nice.
Our Mazda projects the speed, cruise control status, and icons for vehicles next to us on the windshield. It really is very nice - one of the few things about that car that I actually like.
Heh, it’s not digital, but our pickup has small km/h speeds printed on the speedometer, like most cars. But when I was driving in Canada, I found they were nearly illegible (my eyes just weren’t good enough to read the small print). I had to switch to the digital speed display in the dash so I could read my speed in km/h.
