Posting on AIBU for traffic.
I have seen this several times especially in the US where a car seat is placed at the side of the road and an attacker is hiding, waiting for a lone women to investigate it.
I remember a few years ago someone put a lifelike baby inside that was crying.
If you see a car seat on the side of the road do not get out of your vehicle.
Lock the doors and ring the police and ask them to check it out.
