Hmmm...
I've pushed a few cars off of the road.
Probably push started a couple of cars when you could still push start cars.
Picked up my share of glass, nails, and screws off of the road.
(from a local off-street bike path a few days ago).
Oh, I found a couple of women who had lost their paddles while floating down the Willamette River, and managed to get to the bike path side of the river. I had my bike trailer with me at the time, we deflated their boats, and walked the boats to the nearest road access, about a half mile away.
So far no saving babies, but I'll keep my eyes open for babies in distress.
