>biking on the sidewalk in front of the house should be a low risk activity for a 2nd and 4th grader if done together This is still a conservative view compared to 30 years ago, when it was acceptable for a lone 5 year old to learn to ride a bike on a suburban sidewalk relatively unsupervised (yes, really!). You may be on the liberal end of the modern Overton window, but you've been dragged along just like the rest of us.
