If a car drove towards me, and the road kept on stretching between us so that the car would never reach me or atleast take longer to do so, the stretching of the road would violate the conservation of energy.
No, it wouldn't. That's the point. You might argue the stretching violates conservation (it doesn't, by the way), but not the car's energy or it's use thereof.

(It does by the way) - read what the actual cosmologist has to say, then get back to me.
