Cars are designed to transport people from place to place, and cause death as an unfortunate side effect. Guns are designed to propel bullets at high speed, and cause death as the intended primary effect.
There can be other conversations about the effectiveness of public transportation, and how the US infrastructure was designed around cars instead of buses/trains, but there is a pretty big difference beyond the number of deaths caused.
What is your point? Everyone knows cars and guns are designed differently. Seems like you are trying to rationalize irrational terror. Statistics show a student should logically be more wary of dying in a car wreck on the drive to/from school than getting shot at school. Are you suggesting our students should ignore math?
