All 100% EV to Boston and back, I used the shortest way there and went through all the towns without use of any highways. Same as the Cambridge trip, daylight trip was in the 200 teens MPGe, and night return trip was about 40MPGe lower due to headlights. Same exact path today there and back, the GPS wanted to deviate to another way (to 109) and I stayed on 1A like the way I came in. Reason being 109 has a big hill to climb into my town that eats about 10% battery, and that's always a challenge on a night trip back home from long distance EV driving.
Attached trip pictures below. Traffic during the evening on the way in extended the time to get there, on the way home smooth sailing.
