Don't mean to "fan the flames" but I thought I'd just update my more recent experience in determining the effective range of the Bolt based on my driving style.
So, after driving the Bolt on 3 different occasions over the past week for 60-80 RT journeys at freeway speeds (70-80 mph) and over some very hilly terrain, my the estimated mid-range estimate has dropped from a previous average mid-range estimate of around 210 miles (when I mainly drove it locally around town on city streets) down to only 185 miles today. These estimates were each made after a full recharge.
This tells me that the Bolt is NOT likely to make it to and from the City (160-180 miles) the way I drive and I would NOT even bother to try doing it unless I know that I have at least 2-4 hours to partially recharge the battery on a free L2 while in town. However, the reality is that I don't want to "waste" the time waiting for the Bolt to recharge while in town, so it doesn't look like I'll ever drive it there.
