Yea you're right I just went to play on Kentucky's version of the autobahn: I-71 between Cincinnati and Louisville. Drove Cincinnati to Louisville up I 65 to Rte50 back to Cincinnati. But if you have never been on I 71, the speed limit is 70 MPH and there is absolutely nothing out there. Ergo, in order to not get run over, you should go 80 - 85+ There was at least one time I was 100 +. I was in my LT, thinking about how my Eco would have felt/handled driving at such speeds!!! As I typically found myself doing high speeds w/o knowing about it(one of the reasons I considering to get rid of it earlier). Surprisingly, I still maintained @ 30 MPG even at such speeds in the LT!
