I'm considering trying to use superchargers or free public chargers around my area both at home and at work... got about 20 mile commute. Don't think I'm going to be in my house for that long, so not sure I can justify installing a charger in my garage. It would also be somewhat expensive given my house setup (detached garage far away from the house's main circuit breaker). Anyone else NOT install a charger at their house? Is this a common thing?
