My point was more that insofar as Government Sponsoring is required then I didn't think it wrong to give a handout to the rich
(as being the only people who can currently afford an EV, let's say) in order to promote EV adoption - on the assumption that "EV Adoption is a good thing", and further that if "EV adoption is not only a good thing, but critical" then government sponsoring that is both a Good Thing and important (by whatever means, I have no strong views, except that Government is usually useless and I'd prefer "effective" means pls ...) then I think that's fine - doesn't have to be a gift-to-the-rich, could be a gift to the manufacturer (no use if the only makers [have been] foreign), or something else.
Of course I'm here in part because I personally think that EV adoption is critical (and have chosen to buy a 100K car instead of my usual 25K to be more Eco etc. and because I had previously given VW my business buying their "Blue Motion" Eco cars ... and look where that got me ..)
Here the Gift is capped at £7,500 (from memory) so decreasingly less beneficial the more expensive the car you buy. Its still generous ... plus currently in UK there is no Road Tax for EVs, and Electricity does not include the (very high) Fuel Duty Taxes that are on Petrol etc., so basically not contributing to Road Maintenance fund either, and I also avoid Congestion Charges, am often allowed to park for free (at a Charger in an otherwise paid-for car park), use of Bus Lanes in some circumstances and so on ...
All means of promoting EV adoption, which in the main is currently something only richer people can buy - certainly anyone who has only ever had a second-hand car is not really at the table yet.
Personally I would increase the subsidy by government, and even if
EV could complete on level playing field with ICE, in order to hurry-up adoption - which in turn will increase production, and reap the rewards from economies-of-scale.
