ElonMusk has stated his intention to get EVs to the masses, so this could be the start. I can’t see any reason why Tesla shouldn’t be on the scheme except for cost.
Going back several months I despaired at the lack of EVs on the scheme but to be fair that situation has improved substantially and not even the reduction in the grant has affected the choice detrimentally.
The greater the competition the greater the choice. Bring it on.
