Sorry I was too cryptic for you.
You missed the insinuation that it would be so far in the future of electric development (given the decades it will take for you to recoup your costs) that a 500km charge would take minutes. And since electric cars ALREADY out perform our dinosaur guzzling ship anchors (your shagga included) then the future will only bring even better models.
Bahahaha! Pray tell how you've imagined how a 120kWh charge point could deliver and store enough energy in less than say 30 minutes that would last more than two hours discharge time. Then Raj not only would I take you seriously but you would solve Earth's energy problems and enable electric space travel!
Think about it, you could only travel an hour away (max 137km) before you had to turn back to get another 30 minute charge. Else there'd need to be quite a few charge points to make an effective network, more pervasive than ATMs, every 200km along an established route. Apart from cost, the missing piece in your electric utopia is the time to charge and ability to store.
What we already know for fact is there's a whole thread on your
Electric Dreams mate, to add to your hijack, as it stands on Earth right now domestic electricity rates are around 31¢ per kWh. Do the math and read the fine print, there's no such thing as a free lunch, just free access to the commercial charge point(s). No matter where you fill up, electricity is billed to your energy provider account.
So assuming current rate for domestic energy that's $52 per 250km charge = 20¢ per km versus renewable biomass in a 500hp two tonne V8 with unlimited range = 13¢ per km
Or you could pay for it upfront like a fuel/lease deal offered with conventional cars and pretend the fuel is free for the next
n years. But it's not.
