Gizmodo got to hang out with some Lexus dudes and try out the self parking Lexus LS460. Here's how they describe it:
1. You drive past a parking spot at 12mph or less. The four rear and six front sonar sensors detect the cars, and the gap between them.
2. Putting the car into reverse activates the wide-angle backup camera. There's a little button on the bottom of the screen that looks like a car parking. Hit it. If the spot is more than 6.5 feet longer than the car itself, the car enters Advanced Parking Guidance System mode. This is where the magic happens.
3. Crawl backwards, keeping your foot on the brake. If you touch the gas, or the wheel, the mode shuts itself off. Make sure to stay under 2.5mph, or it'll shut off, too. The wheel, as you can see from the video above, spins itself like its being ghost-driven. The sonar system is constantly measuring distance, beeping with more urgency as you get closer to obstacles.
4. When you're in the spot, the computer will announce that parking is complete.
Pretty amazing tool. Especially if you're like me and the only way you know how to park is to run into stuff until you come to a complete stop.
