Hmm not all disabled/elderly/pram users have access to cars by a long margin.
They may not be big spenders but will be reliable/loyal as long as they are accommodated to some extent.
They have been ignored at best.

Once you encourage people to take their car or get on a bus, they are not going to get off just up the road, but will continue to a shopping centre where the flooring is level and you can cross from shop to shop without waiting 10mins or taking your life in your hands.
Plenty of room for a wheelchair/pram, there are countless lifts/escalators for changing levels in a centre.

Widening the pavements is a positive step and if they can fix the main junction as we all have suggested for decades, fix the underpass to make it accessible, etc, then there might be hope for DR after all.
