Couldn't you use Elon Musk's Boring Company to recreate the missing Ringways as underground tunnels? I remember as an American overseas in 1975 that it was one of the most baffling aspects of driving in London. I don't know if they still do it but the rental car companies would offer to drive you from Central London to the beginning of the freeway. Assuming they took either a bus or the tube back. I took a trip to Bournemouth to see a ham radio buddy and ended up being white knuckled the entire way. After our visit I ended up turning the car in and taking the train back into London!
