The extraordinary extra expense and tendancy for breakdowns for what is a simple system today makes this suggestion extremely doubtful.

It would be useful to have this feature. Since most cars with power windows have an "auto-down" feature on the driver's window it shouldn't be a great expense to do it. Though as many times as I've accidentally set off the panic alarm on my car fumbling for the keys I would want the button to have more than just a little pressure required to activate it.

Sorry, I misinterpreted the suggestion. I thought the "windows" referred to windows on a house. On a car it seems reasonable.

I wouldn't limit control to just the windows. I would include every electrical system in the car. That way you could interact with your vehicle on a much more powerful level. See Vehicle Bluetooth

Aftermarket alarms can add this feature with modules designed to open or close the windows from the remote.

Additional control can be added through extra alarm outputs only limited by the number of 'channels', basically button combinations, the alarm has usually around 4-5.

Try to keep up. Most luxury vehicles already have this capability. I've had this on the last three vehicles I've owned. It is very handy, especially in summer time when you want to aerate your car before getting in. It even does the sunroof.

Auto-down when a car crashes. When a car crashes in to water, beforethe electrics short out, the windows should roll down, or one escapehatch window should blow, so that people don't get trapped inside unable to release the pressure once the power fails. Lives wouldbe saved as people who would otherwise die - be able to escape electric-window tombs. Either that, or make the drivers window set with an alternate manual hand crank.
