Superchargers are intended for on-the-road, long-haul recharge. While your local gas station is used by everyone in the neighborhood, most Tesla drivers, most of the time, will be charging overnight or during work hours at home, work, or a dedicated car park. Which should reduce demand somewhat.
From Google Maps, the Harris Ranch location is presently a single charging station. That is something which should be readily scalable as demand rises.
Your usage pattern at a given Supercharger station would be a factor of total traffic on nearby highways, Tesla ownership, and recharge needs. Present stations are at highway plazas -- not necessarily in high-ticket areas (hello, Harris Ranch and Barstow), but given the vehicle owner demographics and minimum 30 minute linger time, they'll likely offer typical captive-audience amenities, so the time won't be a total loss.
And charging is possible from other outlets, though at 5 miles/hour from 110AC, that's a good (or bad) 60 hours to recover full range. More likely you're getting sufficient charge to get to a higher-rated output.
Further though: so long as queuing depth is one vehicle (that is, you arrive, all chargers are filled, and there are no vehicles in front of you), the mean wait time assuming a 50% charge is 30/n, where n is the number of stations. So, 6 stations, queue depth of 1, you'll wait on average 5 minutes for someone to pull out, extending your total recharge time to 35 minutes. If Tesla strives for this as a 95%+ level of service, it should be tolerable, though high-travel periods (holiday weekends in particular) would tend to be worst-case scenarios.
Correcting myself: mean wait time would be 30/(2*n). As on average you'll arrive when another car is halfway through its charging period. So for a 6-charger station, 2.5 minutes wait time. On average.
