I take it this was data collected on the great FLA trek of 2007/08?

It's really good data to have.

I wish this type of detail was available from the government agencies (EPA/NRCAN) - in addition to the "city vs. hwy" simulations (which is all they are), I'd like to see an actual plot of fuel economy at various steady state speeds. That, I think, would tell us more in the long run.
