Popular truck route from Queens->Bronx was 59th st bridge, left onto 2nd then immediate left onto 59th, and another left onto 1st and take 1st all the way to Willis Ave bridge to beat the RFK bridge (formerly the Triborough) tolls.
The number of trucks I see that are either horribly maintained or purposefully modified to defeat emissions devices spewing massive clouds of black smoke every time they step on the accelerator pedal speaks otherwise to me.
Rolling Coal is absolutely a thing.
This was the claim I was addressing. Truckers (a group that applies to more than just people in NYC) are intentionally giving kids asthma through their choices to defeat or not maintain emissions equipment, I see it every day. Maybe NYC is enforcing their emissions standards enough to no longer make it worth it to truckers there, but don't doubt they'd go back to belching toxic fumes to save a penny if given the chance there. They do it practically everywhere else.
