I've Always Thought These Ordinances Were Weird

But I struggle to find a constitutional argument against them despite it is your personal property parked on your own real estate.

However, is it an offense regardless of the amount of time the car is running? Is thirty seconds a crime?  What is "unattended"? If I can see the car out the window does that meet the definition? And notice the "keys in ignition" part of the ticket. Is a car with a remote starter OK? If so, it's not the wasted emissions that the ordinance is designed to fight but theft. So why isn't it a crime to leave my keys in my car if it is not running?

So many questions on the day the Texas legislature goes back into session to screw some more things up.
