To mepal,
You are only correct if the child was taught how to do it correctly the first time. And then the parent has to make sure the child practices it correctly. Recently, a yeshiva near me- the bochurim started eating across the street from their bais medrash. Not only do they cross with jay walking in front of me while I’m driving, now a lot are playing ball or other things in the street. This street doesn’t barely even have room for two cars to pass in opposite directions and it’s a two-way street. The thought has crossed my mind to hit one of them to teach them a lesson, but of course I would never do such a thing. These are teenagers, whom obviously were never taught about street safety. Even though most people crawl on this street, so they can stop or slow down in order for these kids to get out of the way, it will only take an un-familiar driver who will be speeding, for a tragedy to occur, chas v’sholom!
