Assuming that a car can be steered both left and right, what is the most efficient way of driving it?

Thanks for passive aggressive response @atomowy_grzy. What I was looking for a
was for conditions or scenarios like security or caching that help me understand how to get the best out if. However, by your response I guess I am too stupid to discuss this with you and I need someone willing to help me get out of my ignorance

by calling it on client side which can off load the work on the server but more javascript to send to client.
however, if you need to call the api with some secret info then you should call it on server side

it's not passive aggressive, I'm just highlighting how many aspect there are that would dictate "what is the most efficient", literally hundreds

and how impractically open the question is

would you prefer a "it depends" as an answer? because, realistically, it depends - on lots and lots of factors - and there isn't a master key solution and one perfect answer
