living vicariously
I'm not convinced – as I've said previously – partly because of the advances in technology to get there won't be THAT quick and also because the growth of the network will mean range doesn't become so much of an issue. Like you say, you manage just fine and you do a lot of miles. Looking ahead to some of the productions cars being launched in Frankfurt next month, things like the Volkswagen ID is topping out at 300-ish (claimed) miles. Getting to 500 will take a bit longer than three years IMO.
Not sure why you have picked on 500 miles. How many people drive regularly say from Brighton to Glasgow without stopping for a half hour break. For the vast vast vast majority of people 300 miles is ample.
So long as you can get a quick charge either part way or at your destination super long range becomes less important.
