Warning. If you want to drive the car low, make sure its battery is allowed to balance once a month or so, and then every few months (3-6 they say) drive it down to below 10%, let it sit there for a bit, then charge it up all the way to 100% on an AC charger and again let it balance. That lets the system see the discharge curve of the battery and keeps the GOM honest.
I went down to my last seven miles today, with no qualms. I knew I could make Aberdeen, from what the GOM was telling me, and if I got nervous I could have dropped my speed to conserve range. I did accept when the car asked if it should go into energy-saving mode, but I didn't notice any effect on performance. I've been down to 4% before now.
It's all about knowing which charger (or home) you're headed for, and being comfortable from what the GOM is doing that you're going to make it.
Today was unusual, because the car was serviced yesterday and came back with a factory reset. Once the car was charged back up the GOM was telling me I had 199 miles of range. In your dreams. I've been seeing 145-150 miles lately, and the weather was cold this morning. I knew I had 140 miles to go. So I watched the GOM counting down at the same time as Android Auto was telling me how many miles I still had to go. By half-way I was believing it, with a reported 14 miles in hand. That decreased further as the road is quite hilly before you get to Aberdeen, but the worst it was telling me was 5 miles in hand. I reckoned that by then I was close enough that I wasn't in trouble, and if the 5 miles got any less I could reduce my speed to get more range, but it was all fine.
