You can wait until a parent and child are killed by a speeding motorist.
Then the entire town, lead by the people in authority and the news media demand that something be done about this senseless tragedy.
Someone will then suggest a pedestrian bridge over the busy road.
The politicians and bureaucrats will be at the ribbon cutting ceremony with great fanfare for the opening of the (insert the name of the child killed here) bridge.
Seriously, though, I never did use motorized transport to get to school and seem to have survived pretty well.
