Never met a guy who did that. Only once met a woman who did it, the instructor for a health class in college..Normally when someone says that’s an interesting question, they are trying to put the answer into words, not always an easy task if the answer is complex..So often we ask questions of people that are not absolute yes/no, because in one circumstance it’s yes, and in other circumstances it’s no, but it’s somehow expected a short answer will work. A question with a dozen or more circumstances attached to it, that change the answer for each circumstance, make it impossible to glibly answer “yes” or “no.” Seems like people delight in asking those types of questions, though, somehow expecting a yes or a no..Take this question: is diesel better than gasoline? Can’t be answered with yes or no. For large engines, diesel is generally more efficient than gasoline. For smaller engines, gasoline is typically more efficient. But with the advent of more advanced small diesel engines in the last decade or so, there are small diesel engines that are more efficient than small gasoline engines, which makes the general rule that held during the 20th century debatable. Then there is the 30% reduction in efficiency that 10% ethanol causes in gasoline, which skews the results.
In terms of pollution, it was once a set “diesel produces more particulates” but when low sulfur diesel came into use in the EU and US along with emission controls, it’s now comparable in pollution to gasoline.
