So yes, it appears that it's becoming doable, but maybe not if you're in a hurry
And the trip in that article took 4 days, and the last 200k of the journey was done with the car mandating a 80kph top speed on a single lane national highway? I wish they'd quantify their claimed carbon emissions savings? How do they think the electricity was generated? If they were paying the recharge costs, they would have only saved $100 odd? Personally, for the extra $100 in fuel I'd be happier to halve the trip time
I'm not really for or against electric, I can see there is a space for them in our modern world. An electric car with a 400km range would mean about fought-nightly recharges for my around town driving. But for a big trip, or a trip anywhere away from suburbia, I think it will be a fair while before I'd consider electric.
