Most of those other things, I have seen, but on different projects lol. Like the LED street lamps have been phased in on most streets out here over the past few years. They also upgraded the light-up street signs to have LEDs and replaced the yellowed, cracked, faded glass with shiny new glass.
All of those things were super solid improvements though.
Of course, we could just act like the town is evil, defund everything, and then have them sell the rights-of-way to companies that would almost certainly squeeze the blood out of the infrastructure and place advertising on it.
Maybe they'd put cameras and use machine learning to determine which streets are the busiest, and find out more about the demographics of people who walk the street, so they can decide how long to leave the lights on - oh and sell that data to further profit lol.
I take it you've never been to Japan
I can definetly see how replacing a lowly old pole with one of these annoyance towers can lead to strong opposition even for those not having 5G scares.
