If it’s just for joy riding it’s fine then. I’m more critical of valley roads where there is a lot of traffic. It’s not because cars have reigned supreme there for decades there that we shouldn’t adapt the infrastructure for bikes. It’s a lot of work for sure. But it’s sustainable development.
There’s no need for that, unless parts of the US want independence, like some Scots regarding the UK. But break it all up because it’s too messy, not healthy? That’s what critics of the EU or the UN also say. Myself I’ve always been an advocate of unity and collaboration since it’s the only way we’re gonna be able to solve climate change and every other major world crisis.
