I know this is a new invention and that only 25 have been sold. All in Europe, but I think this would be a great idea everywhere. It does have a motor for hills and before all the kids are on it. It seats 11 kids and goes up to 10 mph.
Too many kids are not walking or biking to school, which is one of the easiest ways for them to be physically active. This would allow the kids to get to school with supervision, but also with physical activity, not just riding in the back of a car.
If you have kids, consider walking or biking with them to school. It will give you a great time to talk to them without the distractions of driving or the radio. Plus, it will make your whole family healthier. There are organizations encouraging this behavior who can organize events in your schools.
