My daughter, a new driver, drove to dance class tonight. This is an 80-mile round trip with a mix of road types including interstate highway. She drove as teenagers do, a little above the speed limit, and still managed a 57mpg round trip in winter temps in New Jersey. For those seeing significantly less, I'd look into the state of your Insight. Check tire pressures, junk-in-the-trunk, and definitely check out your driving style. With an Insight in good repair, I can't fathom a way to get less than 40mpg unless one drives like Ricky Bobby or Cal Naughton, Jr. #shakeandbake
