My take is that it already solves it.

I do no less than eight one-way 1500km trips annually(so that amounts to 12k km during such a period).

I used to do it in one take, but that was over 20h behind the wheel - very dangerous - so now I split them into two legs: one of them 1140km long.

Assuming I started with enough charge for 300km, I would only need to get enough juice for 840km or so - less than 40min overall at this rate which is roughly the amount I spend during my trips on going to the bathroom, eating and leaving the highway for fueling as to not pay the ridiculous on-highway prices.
