The majority of bus users living on those three main corridors are riding into the city centre for work or leisure, because it’s cheaper and easier than taking their car into town - or more likely because they don’t owner a car, (Newcastle has a higher percentage of non-car owners than other areas).

You’re never going to persuade all of people shown in the image linked below who are sat in their private metal boxes to switch to public transport. They are contributing to congestion and pollution and delaying public transport further.

Car is no longer king in cities and it’s about time public transport was prioritised. If you don’t try to improve public transport & make it a more attractive option then you risk losing current patronage, when the aim is to increase it.
