Nice point to raise and it shouldn't matter. Reading glasses are for when the focusing muscles in the eyes weaken, which highlights a concern often dismissed by interface designers; you should not need to use refocusing muscles in a vehicle anyway. They are too slow.
Large font is not just for old people - it's for speed. This is why fighter jets and airliners have Heads-up-displays optically focused at infinity, so the muscles are not needed.
UI designers want to make the best of available screen space, naturally, but they are usually designing sitting at a desk, not doing 120kph, and it can result in the wrong priorities.
