I had a tad bit of range anxiety this weekend. Saturday night I had to drive up to Hudson and back. Not going on any interstates, this is one of those times where you feel like you're in BFE when it comes to charging. It was a little cold, so not ideal temps, and my car was sitting at 90% when I left. I put the route into the Tesla, and also the way back home to see what would happen. It predicted that I could do the drive but get home with 6% battery, which is a little low for my comfort level. I got to Hudson with around 48% battery life, which was about 2% lower than it had predicted. When I went to drive home, it predicted that I would get home at 7% if I didn't stop. I got home at 8% and it never fluctuated outside of 7-9%. With current gas prices, it felt good to plug in at home for cheap.
A year ago, I would have probably not taken the risk and just drove an extra 10 miles to hit the Grinnell chargers on 80, and do a quick 5 minute charge. Another option would have been another 15 miles and hit the Ames chargers on the way home. I don't know why I worry so much, if 8% equal 20-30 miles, I wouldn't be worrying if I was driving a gas car.
On a side note, I hate driving at night in rural Iowa with the deer.
