Without passing judgement on the merits of this one way or the other, I think anything that has a 10+ year deadline is virtually meaningless. It's not in the power of the government that passed this to see it through.
And government has the power to change things. Europe has a 12% BEV share in new cars because of subsidies and regulations: https://cleantechnica.com/2022/05/29/stellantis-wins-1-2-in-...
Norway has a 85% share of BEVs in new cars because of even more government intervention.
In some ways its good, theres companies investing money to develop new cars, its not right to just drop something like this on them, then theres other infrastructure, houses, flats that need chargers etc.
But. Theres always the tendency to make the announcement but not follow it up in any practical way. eg in the UK they're phasing out gas (only) boilers from 2025, but they don't seem to have decided if they're replacing this with hydrogen / methane / heat pumps or what. I don't want to make a multi decadal investment without knowing what the government is going to back.
