Ooh, two sides here!
I live very close to an Underground station. I go to work at 5.45, finish about lunchtime, and guess what - I can NEVER park my car when I finish because of all the people who park there to be near the station. It can sometimes be 7 o'clock in the evening before the space becomes available, meaning I have to walk to where I have parked it (also outside someone's house, so for all I know it's a knock on....) and then move it to my house. So in once sense I hate commuters doing that.
To your question though, if you pay your road tax, if there are no parking restrictions, no dropped kerbs etc, then you have the right to park anywhere you choose. They can clamp you, but it will not be enforceable, and it will be an illegal act for which the police can be called.
Having read my answer, you might realise that there are reasons for people being upset. BTW, you haven't got a green Golf have you?
