If most all speedo's were off 8%, don't you think people would be able to tell, and most would be complaining about it?

Actually, you aren't well-informed about this.
Here is the standard speedometer calibration from the official OEM repair manual for the 1985 Toyota Corolla. As you see, the minimum
standard overindication for the speedometer is +4%, and the standard overindication range is anywhere between +4% to +8% and +4% to +15%, depending on the speed. I believe this is also the case for even the newer Toyota's. Odometer is a different story:
