Volt, not Bolt, that's a different car...anyway the AC unit doesn't seem any better or worse than other modern sedans. The electric heater in winter is a much bigger drain on the battery than the AC unit, the AC draws about 500 watts when on "eco" to maintain temp and about 2kW when running flat out to cool the cabin down quickly when e.g. it's been sitting in the sun a while.
In the summer though there always seem to be three times as many cars on the road at all times, there's much more traffic, and the Boston drivers seem to be three times as aggressive and pissed-off than usual.
MA is in theory one of the safer states vis a vis traffic fatalities and injuries statistics to drive in but one of the worst when it comes to just sheer number of accidents and fender-bender insurance payouts and general whack-offery.
The old saw is "Massachusetts drivers drive like they want to kill _you_, Rhode Island drivers drive like they want to kill _themselves_"
