Certainly, but with a warranty based on hard numbers, a liquid cooled TMS, and a much longer range to start, is there currently any other semi-affordable BEV besides Tesla that's likely to still be usable for most people's commute when the pack's eight or ten years old? 238 x .6 = 142.8, which is to say that even with a battery ready for warranty replacement, it's still going to have about as much range as the 2018 LEAF does when brand new, and there's no doubt which one's going to suffer greater degradation due to heat.
If the Bolt is bought to carry out LEAF range type tasks then you are right, but if it is bought to carry out 200 mile range type tasks then unexpected, early degradation down to 60% of new is a problem.
Which brings us back to my point: we don't know yet if the Bolt will be good for a long run of time, and the Volt does not really inform us one way or another.
IMO, anyone buying any BEV with range similar to the Bolt's for routine 200 mile tasks is asking for trouble, short but especially long-term. All BEVs have to allow a large margin for weather, terrain, HVAC use and degradation and/or restrictive SoC range to slow that down. Personally, I think any BEV's routine range for any but initial usage should be considered no more than 2/3rds of max, and in many cases less. Anyone anticipating keeping the car for a decade or more should probably consider 1/3rd as the reliable long-term range capability, until proven otherwise. As we've only had production Li-ion BEVs for 7 years now (the Roadster being more of a proof-of concept IMO), there's little basis for counting on more as yet.
