why do some more "conservative/traditional" jews walk in the road on sabbath?

(i apologize for using the wrong terminology but I am unsure the specific branch of judaism. I believe orthodox but I am not sure 🙂

i apologize for asking a weird question. But sometimes I see very “traditional” more “conservative” jews (orthodox I believe) walking in the middle of the road right near temple on sabbath. (not a huge amount but sometimes 3-4 usually men but if their are women it looks like the men are accompanying the women who are wearing more conservative and plain dresses while the men wear dark conservative suits)

(my neighborhood is understanding so we take less busier roads near their temple but it is something I observed but am worried about asking)

is it something to do with observing the “no driving” rule on shabbat?

I heard an article about it too https://www.cjnews.com/perspectives/opinions/vale-why-do-the-orthodox-walk-on-the-road-on-shabbat
