I once thought that was going to happen to my son: he was six months old at the time. Although we didn't have a car back then either, it does make you see things very differently.I use the bike over the car in all possible circumstances, for environmental reasons. I reformed and became very anti air pollution following the death of neighbours daughter from asthma, who I unsuccessfully gave CPR to. That kind of shizzle gives you a major recalibration.
As an aside, I've never seen an ambulance move as fast as the one coming to our apartment that day.
