> But also maybe kids just enjoy different things nowadays
I think this may be true, but also I think parents might find it easier to let their kid play video games in their room where they think they are safe compared to letting them roam around unsupervised. I had friends whose parents thought we were bad kids because we wouldn't know where would go that day, so when they asked "where are you going" and we said "idk, to the creek or pizza or wherever we find interesting" they would think we were up to no good since we didn't have a plan.
The funny thing is back then there were no sidewalks or shoulders at all, and kids biked everywhere until old and lucky enough to drive. Now, there are extensive sidewalks on all the main roads, but the only people using them are middle aged dog walkers.
Sadly never crossed my mind to figure out what time the lights turned on, and expand my radius further.
