Wheelchair or pushchairs: Who should take priority?

Disabled Yorkshire campaigner Doug Paulley has claimed an important victory in his battle for wheelchair users to have priority use for wheelchair space on buses.  Read here.
At the time Mr Paulley attempted to board, a woman with a sleeping child in a pushchair occupied this space. She was asked by the driver to fold down the chair and move, however she refused, stating that her pram didn't fold down. Mr Paulley had to wait for the next bus and as a result he missed a connecting train for an appointment. Mr Paulley brought a case against FirstGroup after he claimed that their policy 'requesting, not requiring' able bodied passengers to move was unlawful disability discrimination.  
As a mum who uses the bus I have been asked to get off with my pram for a wheelchair user and I did so without a second thought. It's not the only time I have been asked to get off a bus, and I am sure that it won't be the last. I remember feeling very embarrassed the first time it happened, but with a little help from a friendly gentleman at the bus stop I was alright. Knowing that I had to walk the rest of the way wasn't the highlight of my day but I know that I did the decent thing and moved for someone who was in more need. I will always try and be accommodating to anyone, whether they have a disability or not.
I cannot actually believe that a case such as this had to go that far and to Supreme Court. Isn't it common decency to be polite to one another, not to think that one should have priority over the other. A person in a wheelchair has no choice about needing to take up that space, a pram can and should be folded away when asked despite its inconvenience. As I can only imagine how inconvenient it must be to travel by bus when you're a wheelchair user and only to find a mother and her baby in the space who think that their baby's comfort should come before your physical needs.
In light of all this victory for wheelchair users having a priority over parents with prams. It has left me with a few question being one of those parents who use the bus. Where exactly does it leave us parents? Being told and shamed off the bus, perhaps leading to more problems than actually solving. I know that not many parents asked to get off a bus would be too happy to pay for their fair again. I am so happy that Doug Paulley won his case, its a significant cultural change but don't you think  that in this day and age there is enough room for both, we all need to be more polite, considerate and accommodate others when their need is greater than ours.
