woodydel: don't over-react, please. ("Why don't you say something about my big fat gas guzzling motorhome while you're at it.")

I think asking if a driver has really considered their vehicle choice is a legitimate question. Though obviously this can rub some vehicle owners the wrong way (some people are more defensive than others).

Having said that, it's the questioner's responsibility to do it in a way that isn't abrasive or insulting, and doesn't completely ignore the O.P.'s original question.

It's all about keeping things respectful & civil.

But I also think you're right: a small change is better than none.
