If you put a GPS on the dash of a modern car with an electronic speedo you'll most likely find that you are actually doing around 4kmh less than what you thunk you were
i discovered in vic that there are radar speed checks that tell you how fast you are going, my ute was doing 5km less at 110km/h which is exactly what my GPS was telling me
Then got pulled over outside ceduna for a rego check, i asked the copper how fast he radared me at and the answer was exactly what my gps was telling me
