I have a daily one way commute of 25 miles. I have a 12 bar 2013 leaf (late year model), with probably about 10-12 % capacity loss so far.. My drive is a mix of city/backroad (30-60mph average). I get home with about 28-38% left on my pack depending on traffic/road/weather conditions. I would imagine if I was driving closer to an average speed of 60-65MPH, I would probably end up with far less. If your errands are closer to home, you would be fine as you could estimate what you can and cant do. But, I would not take chances running a bunch of errands at my work location. I do go out and get lunch on occasion (probably about 4 miles max roundtrip away from work).
There's no real 'detour' route for me on the way home once I get on the main road, so if it closed, I would have to drive back to the town I work in and charge up, or pull over and wait it out. I normally check road conditions before I leave anyways. You need to know if you can afford to take a detour route with your range should that come into play.
That being said, I've yet to encounter a problem with my commute and my car fits 95% of my travel needs currently. When I get home, I put the car on the charger if I anticipate using it after work. After an hours worth of charge on my L2 27A charging station, it's ready for any errands I have to run.
Love my leaf and look forward to my next longer range EV in a few years.
