Or Bob could take his 10-mile Prius route, and just drive that 35 miles per hour leg faster (51 miles per hour?). and maybe on the freeway (to avoid 2 lights), which would minimize the time difference, yet he'd still get significantly better MPG than in the Echo. This could boost his hourly rate.
I'm sick, I know...

This is more of what I was thinking of, in terms of the same route with non & hy cars. Since the % highway/city can be assessed from Bob's information. It would be interesting to take the EPA (2008 & pre-2008) and use that information to model the observed MPG. I think there is a "fudge" factor needed to model the relationship and I suspect it will be different for the non & hyb. Hopefully with the model, we could take EPA info for a Hummer, Hybrid Altima, Diesel Jetta, etc and get a fairly accurate estimate of expected MPG on Bob's route.
The concept of modeling is based a lot on my experience with 10 different non-hyb cars over the past 15 years that I drove the same routes, work 46 mile RT and vacation 312 mile RT. I always observed mpg that mapped well to the cars EPA numbers and the characteristics of the route. However, I have no hands on hybrid info... yet
