Generally pedestrians have the right of way at crossings (unless it's controlled with a light) in my state and neighboring states, most crosswalks even have signs that inform you to yield to pedestrians.
So the scenario is
A) you have transitions that work 90% of the time and a pair of prescription sunglasses for the times they don't
Or
B) you have regular glasses, and still have prescription sunglasses.
Option a means 90% of the time you don't need to carry an additional pair of glasses with you.
I used transition lenses for a decade, they are great.
But if my plane lands at 9am local time, I know it’s the morning at least and I can plan my day appropriately (stores will be open or opening soon instead of just closing for example)
If I land somewhere at 9am local time I know that the bank will be open when I land and it will be day time.
If everyone is on the same time and I travel somewhere it will be a complete surprise (or I will have to figure it out before hand) whether or not it will be the middle of the night or the middle of the day.
