The world has gone iPhone crazy since Apple released v2.0 of its sleek mobile device, and while GPS and 3G have been big draws, the multitude of available software apps in the new App Store has been the real wild card. One app that has us really psyched is a new automotive performance meter called Dynolicious from BunsenTech. It uses the accelerometer inside the iPhone to let you record 0-10 through 0-100 times, quarter mile and trap speed, Lateral Gs, horsepower and more. Results are also displayed in real-time on the phone itself with graphs and a speedometer. You can also configure the tool with updates to your car, weight, before and after performance measurements, and keep a complete history of all your runs.

This is the JATY DR7200 GPS, and it does a lot more than just tell you where you are and how to get where you're going on that 7-inch screen. You see, it's got an integrated breathalyzer, too, so it'll also tell you whether you should even be trying to get where you're going. Blow "over" and you get a standard BAC readout, a red "OVER" warning, and if that's not enough, a yellow skull and crossbones to drive home the point that, well, you really shouldn't be driving at all. In addition to all that, it supports just about every techno-acronym you can imagine (USB, MP3, DiVX, JPEG, MPEG, etc.), so if you're in no shape to drive, you can at least watch a movie on the thing while you wait it out. Want one? Just run on down to the local electronics store...in Korea.

We've known for a while that the new iPhone 3G would have the magic of GPS, but we didn't fully realize how that power might benefit car owners. While we've seen a few semi-cool, car-centric applications available for the device -- from mpg calculators to maintenance reminders -- this program could prove the most useful for the forgetful among us.

After parking your car at a crowded shopping mall, users of G-Park tell their iPhone where their car is. When they wrap up their shopping, the application will provide directions back to the car.

The Internets are abuzz with the announcement of an all-new iPhone, and with features like 3G data connections, new applications and GPS navigation, we're excited too. If you've been making plans to produce your own navigation app for iPhone 2.0, however, you may not be all that thrilled. A closer look at the iPhone SDK agreement shows that creating software for "real-time route guidance" is forbidden. This may mean that the creative kids at Cupertino aren't going to let anyone compete with the the Google maps solution it's already settled on.

Road maps produced by the California State Automobile Association, long appreciated by travelers and cartographers for their utility and beauty, are going the way of car-hops, drive-ins and high-test gas.

As of today, we're taking bets to see how long it will take before people realize that "GPS" does not stand for "Auto Pilot." The latest "But the GPS told me to..." story is brought to you by a charter bus driver in Seattle. Piloting a coach through the Washington Arboretum -- as the GPS instructed him -- the driver ignored, or didn't see, or didn't believe (take your pick) the flashing lights and sign warning him that his 11-foot-high bus was too tall for the looming 9-foot concrete overpass.

Microsoft's got a smarter way to keep you out of snarls.

The UK's Department for Transportation (DfT) is trying to put an end to situations like the one you see above. A woman headed to a christening party, paying attention to her satnav -- and little else, apparently -- drove down a road marked "Unsuitable for motor vehicles," and then drove into a swollen river because that's what her navi told her to do.
