Speed changes over the route ... Being within +/- 5MPH of posted limit tells us exactly what is needed to be known in relation to the claim of "pretty slow".
No matter what the speed limit is ... me staying within +/- 5 MPH from that posted speed limit ... is not "Pretty Slow".
The only way around that "pretty slow" claim is if you claim that only doing 5mph faster than the posted speed limit is itself "pretty slow"
My route contains a mix of many conditions ... suburbia ~35mph , highway ~65mph , bumper to bumper ~5mph , etc... where it is posted for 35 , I stay +/-5 from that ... where it is posted 55 I stay +/- 5 of that ... etc... posted speed limit is not , "pretty slow"

Here's another example of some of the accuracy issue from gas pumps.
Link
Arizona May 2007 Had
6 pumps found off up to 200 Cubic Inches out of 231 Cubic Inches in a Gallon
~86% error
6 other up to 32 Cubic Inches off ( ~13% Error )
8 others up to 17 Cubic Inches off ( ~7% error )
(Arizona had at the time a state requirement to be within 6 cubic Inches)
~2.6% error ( if the pump was 2.5% off they passed and got a sticker no fine )
more interesting is that at that time Arizona had a upper end cap limit on fines ... $5,000 per pump ... $50,000 per owner.
So if a owner owns many gas stations ... he can only be fined a maximum of $50,000 per year ... no matter how often his pumps are wrong , or how often they are wrong , or by how much.
