Until electric vehicles are like-for-like with petrol/diesel, I'm unlikely to buy one. And by this I mean range, power and price. I can buy a MB/Audi/BMW, 3.0 litre diesel or petrol, that's 0-60 in 6s or less depending on version, a full tank range that is 500 miles for petrol and 700-800 for diesel. And I can buy that starting at £30k.
The closest similar performance, and I hope to be corrected, is the top end Teslas, where you pay more and more for the batteries. A Model S long range, is £83k, 50k more.
The article is probably correct, because governments are incentivising electric cars. And the "demand" and "supply" by manufacturers is also pushing in that direction.
