The dealers have been thrown in at the deep end alright.
Years and years of plodding along on pretty standard ICE cars, then BOOM !.
Then like a shoot completely out of the blue :-
"What the hell is this thing, it's a WHAT ..... a electric car, what the hell is one of them ?".
Like your first visit to the local swimming baths as a child and you mistake the deep end from the shallow end.
Similar feeling of fear when you first jump in !.
The dealers / Tech's may have found the baptism of fire a little easier to deal with, if they had a PHEV to deal with first, before a full on BEV.
Some - but not all, are going to drown in the technical tidal wave of information.
Sink or swim people - there is nothing in between I am afraid.
It's takes a lot of hard work and time to build up a good reputation that people can trust.
A BAD reputation can be achieved in weeks, but can last for years and years.
