That's a great question. Model 3 owners pay to use superchargers where S/X owners typically do not. That said, it's not prohibitively expensive (26c/kWh in CA where it cost me 16c/kWh to home charge, off-peak only, in tier 1 (tip: I'm not in tier 1!) Because it's not prohibitively expensive, Model 3 owners will use them fairly regularly, but not to replace home charging in a way an S/X owner might. For the most part. Right before our 3 arrived new superchargers went in within 5mi from my house; 1 in East Palo Alto and 1 in San Carlos. They're virtually everywhere around the bay area now, so they've been pretty good at quick rollout of urban superchargers, and it FEELS LIKE they can keep up with demand, here at least. When I check on the map they're busy but never full.
