Vehicular cycling for transportation is unfortunately necessary in many places. It's wise to learn the skills to survive when you must share the road with all kinds of vehicles. I often fear for those I see on the road who do not have these skills.
But there is no future for cycling as transportation if there are no safe places for kids to learn and explore, and there is very little future if the experience remains one that only daredevils and thrill seekers can enjoy.
Forester's vision would (and may) be the death of transportation cycling.
