I think if you're over 50ish, it just seems pretty unlikely.
When my time on a tank of fuel is spent mostly at highway speeds, the average speed is still in the middle and high 30s on average. Sometimes in the 40s and rarely higher, if on longer trips. But we've not taken a trip that required multiple stops for fuel since I started the log, our destinations since have been within range of a tank of fuel and always contain a couple of stops, a diabetic can only travel so long without stopping!
