reminds me of when I see parents teaching a kid how to ride a bike, or just going out with their kids after dinner, parents walking with kid way ahead on their bike. those parents have no control over that kid. they can't make them stop at a road crossing 900 feet ahead. they are powerless. that's not how I managed my kids when they started learning how to hike in the woods & ride bikes. we stayed together. sorry for the rant, I'm remembering the 6yr old that was run over while riding with their parents on a bike trail. the kid roade across the intersection w/o stopping & there was high grass at the trail obscuring the driver's view of any oncoming pedestrian or bike traffic. so avoidable
