There are a few negatives towards a rapid disruption, currently battery production capacity, and the "chip" shortage together with an informal price fixing for the various segments of electric vehicles, which hasn't been disrupted by any of the legacy manufacturers stepping out of line or indeed by the likes of TESLA. The closest they will come is if Renault allow the Dacia Spring loose and don't throttle production to avoid damage to their own sales of the Twingo. "A" segment electric vehicles kick off at £20,000 ish to get them out of the showroom and the overpricing follows that up the scale. When all the manufacturers, start making enough of them the windscreen sticker price of EV and ICE will come together, By 2030 even if auto manufacturers still find markets for ICE around the world, in general the majority of their production will be Electric Vehicles.
Even if the market for new cars in 2030 is half of what it is in 2021, it will be dominated by EV's whether in personal use/shared use/subscription/hire/city mobility applications etc.
One thing is for sure EV's are on the ladders, while ICE is sliding down the snakes.
Best deal in electric cars is of course a second hand Leaf
