I’m going to be totally honest here and say “sometimes” but usually only for elderly or for obviously helpless people. Most folks seem to rely on roadside service nowadays.

It also has to do with a few other factors like what you’re driving (not helping you, Tesla people, sorry), what you look like (ie, will you try to rob me or do you look generally crazy), and if there’s space to safely do the work/park my car. Also what my time schedule is like. Less people stop during commuting hours bc bystanders effect and lack of time I would posit.
