For an area of incredible beauty, which relies almost exclusively on tourism, for most of its residents.
To ban cars, because the area simply cannot cope with the bulk of summer traffic, seems a bit pointless.
Businesses will suffer, when visitors are denied access to the area, and how many shuttle bus services will be required, when thousands of visitors descend on the hot spots all at once.
The sherpa bus system, here in Snowdonia, does not cater for as many visitors as does the Lakes.
On the rare occasions when i have been to Cumbria, the sheer bulk of traffic and number of visitors, takes my breath away, no where here in Snowdonia gets that much footfall, not even llanberis.
Snowdonia is busy in the Summer, but i recon the number of visitors to Windermere, Keswick and the other popular areas, who are not there to walk the fells, far out numbers that of Snowdonia.
Trying to ban cars, to the most popular spots, will destroy the tourism in the long term, and like Gwynedd in North Wales, Cumbria needs the tourist to survive.
