We go for walks just about every day. Sometimes I feel like I'm being paranoid about strapping her in the [car]seat in the stroller. But once we get near any road with cars, I get nervous and will strap her in if she isn't already. I don't know if I have an irrational fear, but the thought of her stroller getting hit and her flying out does cross my mind. FWIW, our speed limits around here are 50-55mph and people tend to still go about 40mph in the neighborhoods.
Do you always strap your LO in the stroller for walks? If not, when did you stop? Like when they could walk? Or did you worry they'd jump out of the seat then on their own?
