I grew up in an area outside the US, and quite a bit more to the north. I still remember how for several weeks each year I had to walk to school in the dark, sometimes having issues with seeing where I was walking.

The DST changes abruptly made everything visible again. Around that time we were also getting a permanent snow cover. And the whiteness of the snow significantly improved visibility for the rest of the winter.

So I don't think that the concerns are completely unfounded, but they are probably not as dire either.
