A desperate couple from Sao Paulo were forced to phone relatives in Brazil for help, when they found themselves marooned in the West Country.
The pair, whose rented car ran off the road in Cornwall, said the ordeal had been terrifying.
‘We had to book into a B&B outside St Austell, miles from any civilisation, existing on pasties and re-runs of the 1970s TV series, Poldark,’ they said.
A spokesperson for Roadside Rescue warned, ‘We get this all the time. Tourists underestimate the difficulties of travelling in the remoter parts of the West Country, where conditions may be more primitive than they are used to. It can be a jungle down there.’
