But you know, it isn't a concern only for older people. My vision, as corrected by my glasses, is 20/20! So unless my eye doctor is an idiot, my vision is as good as it should be for anyone at any age (except for the effects of cataracts that make it a bit harder to drive at night in the face of all the newer cars and trucks with bright lights).I'm thinking the average age of the engineers at Tesla is probably half my age, or less. It will be a long time before they have the trouble, we seniors have. Although I'm an Elon fan, I'm hoping his eyesight degrades soon. If that should happen, we would see font adjustments very quickly.
