"Polestar’s calculations, based on the average global energy mix, show it would take 70,000 miles before the 2 had a CO2 advantage over the petrol XC40." I wonder at which point you need to replace (and recycle) the batteries and start adding to the tally again?

I just wish manufacturers could be encouraged to drastically reduce the weight and size of their cars. The heavier the car the larger amount of particulates from tyres too. Massive SUVs and cars mean bigger batteries and more weight. Yes, SUVs are already capable of carrying the new technology and extra weight but they're also receiving the subsidies to allow people to actually lease and drive them. I do see taxation based on weight coming though, it's just when (I think the French are looking into it, they're certainly looking into big taxes for anything producing even slightly high emmissions). There's a theory the large SUV and uneconomical car will die out as our children change their lifestyle habits (and possibly become embarrassed by our excesses!) but for now cars are all going in a worrying direction.
