That is correct. Whether you regard that as progress I don't know.
Here is some interesting analysis which confirms your point of view. It's not entirely up to date. My impression is that the number of cars in the City centre has fallen significantly in the last 18 months as the Oxford Rd corridor opened.
Here is a graphic which details projected population growth. See panel on the left regarding the City Centre population.
That is the context for public transport in Manchester and why there is a shift from car to walking and cycling. The crane count tells its own tale. There is a surge in people living, working and studying in the City Centre. Students are moving from Fallowfield into the City centre. That means that the City centre transport in focused less on the car.
This has a knock on effect for CIty fans as we of course use Manchester's transport infrastructure. Basically if you a car driver, then the City council does not really want you (my interpretation not theirs, they want you out of the car, and onto your bike, feet, or the bus).
Potential solution if there is a North Stand Expansion, and transport is an issue in 2-3 years time:
Give Seasoncard holders an option to buy discounted travel on the buses, and make more buses available. Get Stagecoach staff to load more than 1-2 buses at a time.
I am not convinced that there actually is a problem beyond car drivers, and tram users, but if there is, this is what I would do
