Can't start a fire without a spark(line)

So you've made some predictions, you've checked their accuracy, and you see that crashes with multiple vehicles tend to cause the most injuries. This isn't all that suprising. Since you're charged with public safety, your task is to see how to use your resources to make the roads safer without spending all day creating dashboards.
