    Would that work?
    But then there's a switch

    Someone needs to do research about how car manufacturers solved this pesky issue.

    well, a toggle switch, right?

    Like when you turn your key from AC to ACC, thats basicly just a toggle switch, right? Then you turn the key to engine start, hold it till it starts, then let go and it falls back to ACC.

    Thats just Like setting a toggle switch to ACC, pushing/holding a momentary switch to start the engine, the let go of the momentary switch, and only the ACC toggle is active.


    Then to turn the car off, you set the toggle to AC, and when you get far enough away, the car locks and turns off on its own due to proximity.

    Yeh, the normal key is a toggle switch with feedback.

    Now... we'd have to figure out if the engine is on.

    For myself, I'd start up the computer when I touched the door handle and turn it off when I turn off my engine. Why? Because I use my car as my locker. I go to my car everyday, pop the turnk, change my books, and head back to class. No need to start up carputer every time.

    true, when I get my car, I will most likely be in a similar situation. I live off campus, and would most likely just load all the books and stuff I need for the day into my trunk, and go back and forth between classes.

    But then you need to wait for the computer to boot up when you are going somewhere. I would really prefer not to have to wait for the computer to boot when I intend to go inside the actual car.

    How can that be solved?

    Have the computer turn on when you start your engine

    what's wrong with the computer turning on and off all day?

    <edit>
    not even on/off, just hybernate/unhybernate.

    <edit>
    I guess it might wear the hard drives more than usual, but not more so than in a desktop that is on 24/7.

    Are you sure that the Lexus syetm has AC and ACC, and not Just ACC, as you guys call it.

    I was thinking, get close to the car, doors unlock, and it goes into ACC. Computer starts up. Press button for the starter. Drive.

    Park. Either press button to shut off engine, or put in park, get out of car. Walk away, lose ACC, car turns off, and doors lock.

    If you want AC, then you can put a toggle switch that you can switch when you want just AC, but in normal mode, it just uses ACC.

    Yeh, it wouldn't be too good for the HDs. Plus think about the battery. Kind of pointless turning it on and then off.

    I haven't seen the newer models with the engine start button. I was talking about the system in the LS430... it has a sort of key feature.
    "Smart Key Entry

    Simply approach the car and grip the door handle with Smart Key in your pocket and the doors unlock. You can also open the boot and turn the ignition with similar ease. In addition, smart illumination turns on the door and interior lighting offering a warm welcome on dark nights."

    [edit]: good read
