People do think "yes we can" that doesn't suddenly make it a simple endeavor or even a practical or affordable solution to hurredly jump in to EV's that don't meet a lot of people's needs and would be impossible to recharge if you were out and about and suddenly finding yourself low on power,or needing power after a long drive an having no way to do it. Yes we can works,but again it's not just something whgere you say "yes we can" and all of the sudden you're just done and all bunnies,flowers and happy clouds. It takes work to accomplish,the work is already being done,but the technologies are NOT there yet. Otherwise why in the world don't we just say "yes we can" to spaceships and fusionpower and just magically hav ethat appear instead. The appollo program started from nazi rocket technology which was actually not too far off from where it ended up and is STILL USED TODAY.
