Hi everyone, am new to the forum and i was wondering if anyone can give me some tips on what would cause my speedo to show 70mph when it's actually doing 62-63mph (friend alongside and sat nav reading)
What's a Yard, I remember my Grandad used to mention them !!! :lol:xacre said:Hi RJW
You need to measure every yard you cover to get an accurate reading of the speed you travel at.
So does a Sat Nav measure its points in 1 metre, 10 metre or possibly 100 metre bits for the purpose of speed readings
