I plan to take day trips in mine...maybe even a couple hundred miles at a time. We have some fantastic scenic roads in Hill Country Texas. One thing I have noticed is that if you go to Google maps and find a location and select your starting point, then click on bicycle route, you find there are ways to avoid interstates if you want. Call me crazy, but I will also do some interstate riding. That far right lane will work and once you are in and around cities, all traffic has to slow down well under 70 mph anyway. Of course all our interstates also have access roads right next to them, so that works too. 100 mpg sure sounds good to me and I am looking forward to doing maintenance on the little bike and maybe even try to get a little more top end out of it. I won't really use the Grom so much around town since I already have a Vespa 300 and the Zero S which are fantastic city/commuting bikes with built-in storage and no shifting.
