The problem here is how to define "need". Those who think a small battery is fine typically cite the 40 mile average commute and believe no car needs more than 90 or 100 miles of range. That's BS in my opinion, unless you want one as a second car. Cars like that do not help the BEV image.Yes, how much battery you NEED to get you where you want to go without pushing the limits uncomfortably. Why is this so confusing?
We go on trips. The longest distance between Superchargers on our most common trip is about 200 miles (more Superchargers would help, but I don't foresee a Supercharger where needed in any reasonable, or unreasonable, time frame because Tesla is fixated on Interstates, and there is no interstate in that area unless you want to go 100 miles out of the way), In winter there can be a 50% loss when there is significant snowfall and/or high winds, also after a few years and many tens of thousands of miles the battery will have lost a bit, so 350-400 miles is really the minimum range to get where we want to go without pushing the limits or trading cars (or installing new batteries) every couple of years (our 85S is now pushing it's limits on nice days--there is the "Don't drive faster than" message). So we can't do our most common trip during winter anymore. I don't see why it's so hard to understand that range is king and will be until all practical EVs are 500+ miles, and maybe 1000 miles for trucks. Promoting smaller batteries harms the adoption of electric vehicles, and generally results in a less pleasant experience.
