The proper etiquette is “not there”. Just because you feel the need doesn’t mean it needs to be here and now. When you’re disrupting other people you’re also causing a hazard to you and them. You can turn on a side street or go around the block or turn into a parking lot so you don’t obstruct traffic don’t cause a hazard, and it may only add a few seconds

Note that your gps would guide you around the block or other place you can do it safely
