It is a requirement of driving to know how fast you are going and it

I have to agree with you here. Under normal circumstances I can keep my
diesel car to a speed limit quite easily, however, I have been driving a
petrol car that I own and another that belongs to our daughter daughter,
for the last 10 days and because they are a little bit more lively, I
find I am breaking the speed limits quite often. Not by more than about
5 MPH though.
