You're missing the point.
I don't cruise around the highway doing 60 either. NJ, like CA, and probably every other state...if you're doing 65 (or posted speed limit) you better be in the right lane (doesn't happen!). People will easily get passed doing 80+mph on most highways.
But point being, to collect data you need to set up a standard. Else, everyone starts running off various points (2700RPMs @ 75mph / 2000RPMs @ 50mph / etc) and this doesn't help.
