Surely, one of the issues is about how wide the pavement is. If, as BarCar suggests, even with cars on, the remaining footpath is plenty wide enough for pedestrians, prams, buggies, wheelchairs, etc, then what's the issue?
In other words, the council could come round, and just make the pavement narrower. Then we have big enough parking spaces, and wide enough pavements. (Unless there is legislation somewhere that determines how wide a pavement should be).
Anyway, regardless of that, the question put by BarCar was, if the council have said it is ok to park on the pavement, which they have, should they then not lower the curb?
The answer is of course they should. And that's regardless of whether or not BigJulie agrees in principle with the council allowing this.
If you want to debate whether or not the council should allow parking on the pavement in the first place, go ahead and start a thread on that. But don't blame BarCar just because they have.
