I don't understand why the trains run so slowly. 20mph seems to be the
max in town.

Faster speeds require a greater distance between trains, so if they ran
faster there would be no improvement in frequency (which tends to be the
thing that matters for most people).

Once the line is signalled for full ATO, speeds will improve (but even
20mph is twice the average car speed in central London).
