A new survey shows that most drivers oppose converting our speed limits and road signs into their metric equivalents, which would bring us in line with the rest of Europe.
Two-thirds of drivers want to stick to miles for speeds, distances and fuel consumption and feet and inches to show heights and widths.
The survey also found that most drivers still work out how much petrol costs in gallons.
Surprisingly the most resistance to change was among young drivers aged 18 to 24, the poll for AA/Populus found.
AA chief Edmund King said: “Going metric would not go down well with the motoring public.”
So hopefully you'll be seeing speed signs you can understand for a long time yet.
