Exactly. Your experience shows the reality of the EPA city estimate. Stop/start in city driving kills MPG. Especially when you need to throw in rapid application of heavy throttle to get around traffic, and even more especially when you take the few opportunities you get to safely wind it out.
In every car I’ve owned, I’ve gotten the best MPG on country roads. They give you the freedom to drive smoothly while driving rapidly. It’s a great feeling, perfect for this car, and promotes good MPG. I wish more of my local roads were like that.
