Given the option, most British motorists would prefer their in-car satellite navigation systems to give directions in the well-modulated tones of the Queen's English as opposed to regional accents.
A survey on Wednesday of 1,337 people found 57% opted for Queen's English compared with just 2% who said they would enjoy being told where to go by someone with a Birmingham accent.
Celtic accents scored relatively well with southern Irish on 19%, Scots on 13% and Welsh 8%, the survey by satnav provider CoPilot Live showed.
"For something as important as getting your directions right, clarity is paramount," said Bernard Lamb of the Queen's English Society.
"What matters most is a form of English that is most understandable by the majority."
According to Michael Kornhauser, the managing director of ALK Technologies - the company behind CoPilot Live - the findings suggest there could be a market for different accents.
