No, it's really not. It's a thought experiment using a clearly fictitious mechanism to get the reader to consider what their experience might be like in completely different circumstances.

For the same reason It's A Wonderful Life and scifi about alternate universes don't have moot points.

This implies that the thing that gets the experience can be separated from one body and attached to another body. It's ridiculous to speculate what this Ford's experience would be if it was a Ferrari.
