There's a safer but equally insane solution off some A-roads in the UK: https://maps.app.goo.gl/vsNMgsfYT7ooa39R9 .

I'm all for expanding cycle networks across major roads, but the wider motorist mindset isn't quite ready for it yet, particularly on my old commuting routines like these arterial routes into London. I'd love to see more cycle lanes but not at the cost of more injured or dead cyclists or scooter users.
