I've searched for an answer to this question, but didn't find it. I'm driving form So Cal to Napa in a couple weeks and entered the route in EV Trip Planner. It shows the actual mileage between Harris Ranch and Dublin to be 150 miles, but says I'll use 235 miles rated. I assume because of elevation? Those that have taken this route (south to north), is this what I should expect? I have an S85. The other question is related to charging in Napa. We're staying in a VRBO with 110 charging available only. Nearly all of the destination chargers on Tesla's SC map show for patrons only. The exception I saw was the River Terrace Inn. Has anyone found the various destination charging places to being more open to non-patrons? Is it customary to offer to pay for charging (or just slip a little cash to the person you're asking)?
