Outdoor lighting is a lot cheaper now than it was in the 1970s. I think we can give it another shot after 50 years. And it's worth pointing out that Arizona has gone without DST for the last 50 years and seems to be doing fine.

Arizona is permanent standard time rather than permanent DST, and is thus unaffected by the permanent-DST winter mornings issue.

Thats only because it’s so hot in Arizona they want to sun to set earlier so it’s cooler in summer evenings.

Interestingly part of the UK approach then was to make street lighting more efficient, around that time a lot of low-pressure sodium lamps were installed. They used so little energy they were only beaten for efficiency by LEDs in this decade, but the monochromatic yellow light was seen as unacceptable by some countries which continued to use inefficient high-pressure mercury then later high-pressure sodium. I miss the humble SOX lamp to be honest, they made night look like night rather than a poor approximation of day. They also had benefits for wildlife, much of which is insensitive to the 589 nm wavelength as well as astronomy where the light is easily filtered out.
