Sorry, I meant a mix of V2 or V3 and destination chargers. More destination chargers if it's a V2 install. I really think this is the best balance for locations where the car might be parked for while (1 to 3 hours, movie, retail shops/mall, near sit down restaurants, etc).
For most people V2 is too fast for an actual sit down dinner (even at somewhere fast like Olive Garden or something). A lot of people get away with it because 80 to 100% takes so long, but then you're tying up a supercharger at like 6 to 12kW when a destination can almost get that same speed and a lot of people only need to charge to like 80%. 30 to 40 minutes is just not enough time to walk somewhere, get seated, eat, and pay a bill and walk back.
If you're shopping for a couple hours and dinner than you'll gain back like ~20kWh or more on a destination charger. If you're seeing a movie it's probably at least 16kWh. You have the freedom to combine that with a supercharge session. Connect for 10 minutes and maybe gain 15 to 25kWh and then go see your movie after moving to a destination. It took 10 extra minutes of your time with your car and you gained like 30kWh. If you've got a long range model 3 and they're V3 that 10 minutes might get you like 25kWh right there and the destination might get you another 25kWh during a 2.5 hour movie.
You need the V2/V3 for long distance travel, but ideally those are near the highway, near restrooms and quick food (coffee or something). If you're in a garage somewhere downtown or a little off the main highways than have a couple V2/V3 for the quick dash in and out but always include destination for people that are down there for a couple hours for an appointment, dinner, movie, shopping, etc.
