Better yet if the old tunnel was turned into pedestrian/cycle.
Then you get proper bus options through the taller tunnel, and proper human-powered options with nobody to run them over, win win.
And I guess we're not replacing lorries/vans for a while yet, so they can use the big tunnel with the busses I guess.
And cars can go via the m25, no need for them in the city. Maybe multi-pasenger/disabled only (incentivises carpooling, helps families who need a cubic meter of junk per baby, and disabled people have genuine needs for their adapted vehicles).
But yeah, the harder cars are to use in cities, the better for everyone (even the drivers often enough, still takes them the same time, but now they're not trapped queuing in a fuming tunnel, instead they're dancing playfully through one-way puzzles... ok, maybe it's not much better for them, but not _much_ worse either).
