Unless you are a victim of other peoples inconsiderate behaviour, you probably do not realise the problems you may be causing.
I had a similar problem for several years where people used to park outside my house and then walk into town to go to work. At the time I had 2 very young children, but was never able to park within 300 metres of my home. This was especially a problem when we did our weekly shopping, as carrying 10 bags of shopping and having 2 small chlidren to tend to was not an easy task. Also, many of my neighbours are elderly, and it was not easy for them either.
I was aware that I had no legal right to park outside my house any more than anyone else, but it was a real problem, and I seriously considered moving home because of it.
Thankfully, there were so many complaints that the local council made it a 'parking permit' area, so now I have no more problems.
