Ok, the UK government under Boris placed a ban on new diesel and petrol cars sold from 2030. A bit obvious that that was going to be unachievable. So Sunak had to push that back to 2035. So, do you feel 2035 is achievable? https://www.bbc.co.uk/news/live/uk-66863110 I say no. It's taken over 100 years to get ICE vehicles and infrastructure where it is, what makes the government think electric is going to achieve that in a decade or two? Even the technology is on steam engine level.
The goal isn't to get everyone into electric cars. No one thinks a grid that can sustain that is achievable in the forseeable future. The goal is to get most people out of cars entirely and stuck in '15 minute cities'. Electric cars are just the cheese in the trap. No realistic projections of reducing carbon emissions are achievable on the currently proposed timetables by merely adapting to renewable technologies (at least not without some miracles, like maybe a UFO that crashes with a free energy engine that runs on garbage or something...). They are only achievable by drastically reducing human activities.
