"Try" to hurt?

Half-burned diesel particulate is absolutely cancerous, it can enter the bloodstream and cross the blood-brain barrier and they're generating clouds of it, probably thousands of times more than what a modern 18 wheeler puts out in half an hour of driving. And they're doing it to someone breathing hard.

If I sprayed some cancerous chemical in someone's face, I'd be arrested within the hour. I'd be on the regional news, even.

The double standards around motor vehicles never cease to amaze.

Wtf people are doing this on purpose? What's wrong with people?
