Sorry, but it seems you don’t actually know anything about diesels.
Diesel exhaust is a Group 1 carcinogen, which causes lung cancer and has a positive association with bladder cancer.[2][3][4][5][6] It contains several substances that are also listed individually as human carcinogens by the IARC.
And if it comes out of the exhaust ports on a dieeel engine is actual diesel exhaust.
All that aside, airosoled diesel still wouldn’t be something you’d want to inhale much of.
In the vein of: i know 98.5% of scientists agree X will harm me, my children, my loved ones and neighbors. The other 1.5% have questionable sponsors, but X is not yet illegal and costs half the price of X-alternative ... so i'm using it one last time. Anyway, if it was really that bad, the gov't would have banned it by now anyway, so ... and then i take another free plastic bag.
