You aren't Maverick and Goose. Don't buzz the tower.

If it's not safe to give them a 4 foot margin, wait a second until the oncoming traffic clears then do it. And when you're passing kids on bikes, slow down to a crawl. There is a good chance they are using 100% of their focus just to stay upright on the bike and go in a straight line. Anything can startle them. Just go super slow. You'll be by them quickly and can go about your business. (And if you see them 5 miles down the road at a rest later, give the kid a high five for making it that far!)
