> Weather situation is the same as walking; you need to dress properly.
I love my ebike but that's not really true. Weather feels much more extreme on a bike, IMO. In the rain I get much wetter on my bike than walking. In the cold the weather hurts my hands and eyes. In the sun I sweat more, because biking is exercise unless I go throttle-only.
And of course there's the danger aspect. Walking in the rain is not a safety risk for me at all. Biking in the rain is not as safe.
So I mostly use my ebike in mild weather conditions and choose other options at the extremes.
And there are countless solution for carrying kids or groceries. We go to kindergarten everyday by bike, a child trailer works very well.

Yes, then you use the car or public transport.
