My mom just bought a brand new Nissan Altima, to replace her dying Pontiac Grand Am, anyway the Nissan has a feature where with the remote keyless entry you can open all the windows. Now we sat there for a while and couldn't see anything but bad things in that. She noted "I don't know how many times I set off my panic alarm or open my trunk by accident, now I could potentially leave my car with its windows open? Not like the window thing makes a big noise like the alarm or a loud click like the trunk. Only thing we could figure is that if its really hot and you wanted to air your car out before you got in.
