Is this true?  Why is there a "cushion" in the speedo?  I have
heard about speedo's being a little slow catching up under
full acceleration, but once you pan out I would expect it to
be within at most a single MPH.  Do all cars have this "built in"
feature?  I'd like to compare my GLX's top speed with other cars, 
but if that cushion varies between manufacturer's, then the whole
point is useless.  Thanks in advance.
