Long distance will continue to be the bane of pure EV's, but once pure EV's reach the magic range of ~300 miles at an affordable price point, that will satisfy the majority of use cases outside of long distance travel, which we all agree will take a long time for pure EV's to manage successfully (although that is more on the infrastructure than the EV itself).
Unless you drive long distances (300+) every day, how often do you really make those long trips?
Under most circumstances, anyone with an EV will be driving less than 100 miles per day, and plugging in at home every night.
No one disagrees, that gas propulsion will be still be around a long time, but by more and more people utilizing EV's when and where possible, it a) reduces the use of gas, b) increases the pressure on buildout of EV infrastructure (and technology), allowing for the eventual coast to coast EV travel.
edit again:
another point to consider as a society, when traveling over 300 miles (or whatever particular range you want to choose), perhaps is time to start looking at other modes of travel, such as plane/train/bus.
it is a change in mindset.
