Recent tweet by @elonmusk (link) mentions "Supercharger and Tesla Urban Charger Network". Is that a single network or two? Could the new network be essentially renamed Superchargers -- So as these chargers would not be used for the lifetime free supercharging or as part of the 400 kWh annual allotment for those without that add-on? If so, brilliant in some ways - owners can still use the Superchargers for road trips. And at the same time, there's an alternative for home/work charging, for those that require it. — hopefully at a reasonable cost.
