Any helmet laws successfully overturned?

If every U.S. jurisdiction had a juvenile helmet law, only 137
lives would be saved. 687 * 0.29 * (2/3) = 137

There would probably be many more lives saved by introducing greater
physical activity to our population of overweight under-exercised children.

How many childrens lives would be saved if there were mandatory helmet laws
for riding in cars?

How many childrens lives would be saved if all speed limits were lowered by
10 mph?
At the same time how much longer would the average motor vehicle trip then
take?

How many childrens lives would be saved here and now and also in
generations to come all over the world if we exchanged our system of
personal combustion engine transportation with mass transportation?

How many children under 21 will be killed directly and indirectly in oil
inspired wars over the next 50 years if our consumption levels aren't
radically reduced?
