Seen a lot of threads recently where loads of people go on about 'well your speedo WILL be 10% out' blah blah blah
I just wondered why people say this as fact. Sure, speedos may have some sort of build tolerance and speed cameras will no doubt have a tolerance to allow for this but think its wrong to assume ALL speedos are 'wrong'.
eg. Using Sat Nav and Origin my old Mk3 speedo read 70 whilst whilst the GPS was about 67, HOWEVER my 2.2 coupe reads 70 MPH and the same sat nav reads 70 occasionally flicking to 69 for a second then back again.
Just wondered if there was anyone actually 'in the know' or wondered what other members experiences were with their Sat Navs / speedos?
(soz for the long post! )
