Will you come to my city in the middle of January when it will be -20 Celsius outside and show how you drive your kids to school on a said electric scooter?
Trying to solve some problem should start from understanding it not from the assumption what everyone has the same lifestyle as you.
Personally I live hours away from the nearest town, use only my bicycle even when it's snowing, and I don't have any heating in the house. So I quite understand that not everyone have the same lifestyle as me :)
But you are right that there will not be a unique solution to the transportation problem. In warmer climate we already have (electric) cargo bikes that are nice for moving kids around in the city, but we'll need more innovation for colder climate and longer distances. And that was exactly my point.
