Incredible bus is also a tunnel

Chinese designers have come up with an innovative cost-effective
public transport system: the tunnel bus.

The remarkable bus straddles two lanes of traffic, allowing cars to
drive underneath while it carries up to 1,200 passengers.

A pretty wild and fanciful idea... paging Boris...

(Being serious - is this really on the agenda in Beijing, even as some
sort of pilot or test scheme? A monorail - perhaps a hanging one - or
otherwise elevated light rail might be a better ways of tackling the
land use issue that I assume is the root of what this idea is trying
to address.)
