No, because the family is going to have two cars anyway.
Once we're at the point where a single vehicle and, say, an ebike are acceptable transit options, then America will have already exceeded it's climate goals. To achieve that, we'd likely need density near that of San Francisco (about 1.10 vehicles per household) or Chicago (about 1.12). Even bike friendly cities that are fairly dense, like Portland, have about 1.5 cars per household.
Again, though, the savings from that would be exceedingly obvious for anyone who chooses this path.
