At the thousands of lake communities here people often drive from their cabin to the boat launch with everyone sitting in the boat. Is this side eye worthy? So far we have kept DS in the car seat and switched him over to the boat once it is in the water.
The also frequently cruise around the village in golf carts with babies on their laps.
Re: S/O no seatbelts
The golf cart... Eh. Not super safe, especially if they share the road with cars, but they aren't tippy, are very stable, and unlike tractors, if you fall beneath it is less likely to crush you.
I don't know if I'd want to golf cart with DS in that situation. I would side eye, but may not really judge.
The boat, I would have a hard time shutting my mouth.
