By the way, turning on a light (at least with incandescent bulbs) involves the prohibition of kindling as well, even according to the view that would permit electricity (at least rabbinically).

I want to consult someone who understands the issues involved on the Sabbath aside from electricity as well. I did not come to receive your opinion in advance. Obviously, Sabbath enjoyment does not permit doing prohibited labor. I am only arguing that there is no prohibited labor involved that would make electricity forbidden, and therefore it is Sabbath enjoyment. After all, electricity did not exist in the time of the Talmud, and I do not think electricity should be forbidden because of creating something new, building, or kindling. This is both from my familiarity with Jewish law, from the fact that Orthodox rabbis rejected one another’s reasons for forbidding it in this matter, and because some branches within the Conservative tradition permitted the use of electricity from the time it was discovered.

The question whether this is Sabbath enjoyment or not has nothing to do with the question whether there is a prohibition involved. So drop the word “therefore” here. The question is whether it is permitted or not, and it really does not matter whether it is Sabbath enjoyment (as stated, cooking delicacies is also Sabbath enjoyment).
I do not know how an electric car works, so I do not know how to answer your question. As I said, in my view using electricity on the Sabbath is forbidden, and as I understand it, it is very likely a Torah-level prohibition.
