About managing this as a family: get a cargo bike, optionally electrically powered. Moves 2-3 young kids, or groceries.
I have seen more cargo bikes with two or three kids in them on some kind of recreational road then I seen parked near grocery store.
For groceries, you just have bike bags. To drops kids at school or daycare, you have kid seats on a normal bicycle (one on a front and one on a back).
And yes, there's plenty of these on the streets, not only owned by rich people.
1500 to 1750 will get you a very good one, and an even better one if you shop for second hand. A bike that costs 1/3rd of what a car costs is overpriced.
