Every number below is computed live from your inputs — nothing hardcoded. Move the sliders and the whole breakdown re-computes. FSD is included in all three options, because that's non-negotiable.
Your office has Level 3 (DC fast) chargers with a 2-hour session cap. Here's the good news: that cap will basically never bind you. A full DC session on a 2022 Model 3 takes under an hour.
A 2022 Model 3 RWD (the one to hunt for) has the LFP pack ≈ 60 kWh — it charges to 100% without battery guilt, and Tesla actually recommends a 100% charge at least weekly. Peak DC rate ≈ 170 kW: 10% → 100% in roughly 50–60 minutes. The 2-hour gate is 2× what you need.
You arrive with ~30% after the 63-mile morning run. Plug in around 9am, the app pings you near full by ~10–10:30, you move the car. That one session (≈ 42 kWh) covers the entire 127-mile round trip with buffer. Do it on both office days and you're fueled for the week.
The 2-hour cap exists so people rotate. Move your car when the app says it's done — campus karma matters and coworkers notice. If the stalls are full when you arrive, wait for the mid-morning shuffle; most people unplug by 10:30.
The car sits. No charging needed, no errands to "top up." If you burn personal miles on weekends, grab a 15-minute Supercharger top-up — or just roll it into your next office day's session.
If work chargers are down or iced by non-EVs, the nearest Supercharger is a 20-minute stop, needed maybe once a month. Precondition the battery via the app on the way there in winter.
Antioch → Menlo Park is not a short drive. Here's the honest picture at 2 days a week.
CA-4 W → CA-242 S → I-680 S → CA-84 W over the Dumbarton Bridge → US-101 S into Menlo Park. About 63–68 miles each way, 127-mile round trip.
80–110 minutes each way in rush hour. Leave Antioch ~7:00am → desk ~8:30. Leave ~5:30pm → home ~7:00–7:15. That's ~3 hours in the car per office day, ~6 hours a week.
Dumbarton is $8.50 westbound with FasTrak (2026 rate, rising yearly to $10.50 by 2030). You pay it every morning; the evening return is free. ≈ $880/year at 2 days/week.
California's Clean Air Vehicle decal program ended Sept 30, 2025. A 2022 Model 3 gets no HOV access — you're in the regular lanes on 680 with everyone else. This is exactly where FSD earns its $99.
The grind — CA-4 through Pittsburg/Concord, 680 through San Ramon, the Dumbarton approach backup — is stop-and-go highway, FSD's best use case. You'll take over for the 84/101 interchange dance and Menlo Park surface streets.
127 miles at ~3.0 mi/kWh ≈ 42 kWh per office day — about 70% of the LFP pack. You arrive home with ~30% left. Totally comfortable, no range anxiety, ever.
