Just a thought (and some common sense)....
Now that the warmer weather is here, please keep in mind there are many owners with EV (electric vehicles) on the road now.
If you encounter a scenario where you notice a pet inside the vehicle on a hot day -- Please DO NOT break glass/window, check by touching the glass (windows/windshield) to determine if the interior temperature is cool/cold compared to outside temps.
EV don't emit any "engine" noises so it can appear as the vehicle is off, while the actual A/C may actually be turned on!
Last thing you want to do is break the glass, startle the dog and it jumps out and runs away due to being frightened by the breakage!
If the vehicle isn't an EV and its hot inside, and the pet appears to be in duress -- immediately look for help or contact local authorities to assist further
