Any firsthand reports of actual tickets or fines being handed out? The article makes reference to “police ticketing unattended vehicle” but no specific citation anywhere for pre-warming. I dunno — seems a bit alarmist to me. Not arguing that there really are such nonsensical laws, but there are many such “laws” that stay on the books for years; e.g., in Kentucky it’s illegal to carry an ice cream cone in your back pocket.
I cant believe ive been breaking the law every time I go to Kentucky!
Here in Colorado, the morning news stations remind their viewers of this law every severely cold morning.
In Maryland, sometime around 1970 or ‘71, I got a ticket for doing exactly that. I forgot how much, but if was a lot.
