When the Leaf first came out, we thought about getting one as a second car. So when the salesman bragged about the number of miles, I asked him to let me know if he could drive to Greenville, SC and back (45 miles or so each way) in summer or winter without a problem - and told him if called me and showed me he did it, I'd buy one.The Chevrolet Bolt has "one pedal driving". One-pedal driving uses highest available level of regenerative braking, which captures otherwise lost energy from deceleration and sends it back to the Bolt EV battery pack. I
The problem of course is we lived in the mountains and it's downhill all the way to Greenville. Thus, the car is always charging to Greenville but there is no place to put the energy once the batteries are full and that wouldn't take long. On the other hand, coming home was uphill and with heat in winter and A/C in summer, there wouldn't be much left to push that car uphill for 45 miles and falling short would be a disaster especially since there were no charging stations outside of town.
Batteries are much better now but the declared distances are only good if you are on flat ground or go uphill first (as you can always turn around and go home if you can't make it as you'll always be charging).
