That sounds very similar to my commute distance wise, but I'm about 80% highway and 20% city. In the morning I'm getting about 20 miles all EV and use about 0.1 gallons of gas. In the evening I use about 0.5 gallons and average between 45-50 mpg's. I wonder if it would be better for you to use the EV later feature and use all EV on your commute home, since the charge will last longer when you drive in stop and go traffic. Just a thought to maximize your mpg's.
