Unfortunately, from what you say, it seems like you had 15 years of parking convenience, that has now been taken away and you're feeling aggrieved?
And it seems as though the bin lorry has also taken advantage of the situation for years by turning around on land which someone has now purchased?
The trouble is that, assuming that your little tarmac lane is a public highway, then none of you has a God given right to park on it just because you live nearby - you may own your house but not the road - fact. But I realise that 99% of people do not want to walk the proverbial length of themselves after parking their cars - that's human nature - but it doesn't mean that you have an entitlement to it - fact.
Unless you all can come to some kind of agreement with the owner of the land, it seems to me that you will have to find elsewhere to park.
