Because if they're using the tube as a daily method of transport and

else.
This argument is going round in a circle.
DLR fully accessible, as is Jubilee Line extension. More and more Tube
stations are becoming accessible as they are refitted.
Which means more and more wheelchair users can use the system - and do.
More stations opened up equals more journeys being made. Its called a
'network'.
