Highly popular with first-floor residents, I should imagine.
It would ruin the streetscape if it were above street level.


The clearance required is also much greater. Subways beneath the roads would
be shallow and could easily come back up to street level.

Although it might be problematic where there are cut-and-cover
Underground lines.
