That don't like the tube? Nobody in their right mind uses a bus for a
car replacement.

Even if you ignore the cost differential (considerable even without
the C charge) bus could potentially be quicker than a car on many
routes because of the buslanes, plus the time taken to park in the
centre. If you are lucky enough to have a bus stop outside your door,
and another right by your destination it could even beat the tube.
