The people who try harder are adding one more way to chew up your daily rental car allowance: for eleven smacks a day, our circuit-geek brothers at Gizmodo report, you'll soon be able to add a WiFi hotspot to your car. The service works via cell towers and offers up speeds somewhere between dialup and DSL. While our Gizbros' thoughts immediately went to in-car smut, we think it'd be a handy tool for getting directions, especially if the car's lacking GPS. Then again, what's a map cost? Two bucks? – Davey G. Johnson

DaimlerChrysler Tests WLAN Car-to-Car Communication System [Internal]

Car-to-car communication has nothing to do with gesturing after a close call on the highway. Futurists foresee a time when cars will use systems of GPS and WiFi tech to let them communicate with each other, relaying information about road conditions and traffic anomalies to prevent smash-ups. DaimlerChrysler is testing such a system — dubbed Willwarn (Wireless Local Danger Warning), with which vehicles are able to "warn" of critical situations picked up by on-board sensors, such as fog, black ice or obstacles such as broken-down car. Such distant early warnings, theoretically, would allow a driver time to take evasive action. As DaimlerChrysler notes in a press release, the system could be enhanced by adding radio beacons at the roadside to give traffic control centers ground reports, as well as transmit information on traffic, construction and other route-related issues. No word on when such a system will be in place, but he who comes out first often sets the standard, a benefit DCX and its suppliers are likely gunning for. – Mike Spinelli

DaimlerChrysler first in the world to effectuate the new technology

In future, motorists will be able to detect danger even if the danger spot lies around the next bend or over the horizon. This has now been successfully verified by DaimlerChrysler experts and their partners in a field test conducted at the conclusion of the "WILLWARN" (Wireless Local Danger Warning) European research project. During the course of this test, five vehicles equipped with WLAN-based radio technology used the "Car-2-X Communication" system to radio details of critical situations detected by their on-board sensors - fog, black ice or obstacles on the road such as broken-down vehicles - to following cars. These early warnings enabled the drivers of the cars behind to prepare for the danger and adapt their speed in plenty of time.

DaimlerChrysler had already tested this technology some six years ago - a world first at the time - by sending the first ever inter-communicating vehicle fleet out onto the road as part of the "FleetNet" research project. This field test demonstrated that WLAN (Wireless Local Area Network) technology, which had already proven a success when used for wireless Internet access, also allowed vehicles to communicate with each other. One of the key benefits is that expensive, fixed-installation transmitting and receiving devices are not required, since the cars themselves act as both transmitters and receivers. The cars establish an ad-hoc radio network and send any necessary warnings to all other vehicles within a radius of around 500 metres. For vehicles outside of this radio range, the cars act as relays and pass on any warnings in much the same way as a relay runner would hand over a baton. No additional sensors are required to detect critical situations, since the necessary information is provided by the anti-lock braking system (ABS), the Electronic Stability Program (ESP ), the steering-angle sensors, the outside thermometer or the navigation system.

The DaimlerChrysler engineers incorporated the key groundwork laid during the course of the "FleetNet" project into the subsequent "NOW" (Network On Wheels) programme (a German cooperation project) and the current "WILLWARN" project. Their aim was to use the experience gained to work together with partners from the automotive components and electronics industries in order to further develop and standardise this promising technology whilst also securing the rights to use the required frequencies. The DaimlerChrysler specialists also supplied information to partners who only joined the project at a later stage, quickly realising that the only way to establish a fully-functioning WLAN radio network that would benefit all road users was to cooperate with other car manufacturers and the relevant authorities. After all, for an ad hoc radio network to be of any use, enough vehicles have to be equipped with the necessary technology.

Radio beacons at the side of the road are required in order to ensure that the first vehicles to be equipped with such a system benefit immediately. These stationary radio nodes could also be used to provide traffic control centres with additional and better information. However, direct contact with the Internet and its numerous fields of application is also possible. In addition to warning motorists of critical situations in advance, the new radio network could therefore also be used to improve the flow of traffic: communicating cars could guide their occupants away from traffic congestion or even prevent tailbacks from occurring at all.

DaimlerChrysler was also one of the instigators behind the European "Car2Car Communication Consortium" and is involved in the American Vehicle-Infrastructure Integration Initiative. These projects lay the political foundations for vehicle communication in Europe and America and have the aim of accelerating the process of standardisation.

Wi-Fi! For Safety! [internal]

Dr. Raja Sengupta of Cal has come up with a novel imminent-collision-awareness idea. First, we kill all the lawyers. Then we equip each car with GPS and a Wi-Fi transmitter. Then, cars talk to each other and decide where they are in relation to each other. It's an interesting idea, and GM's throwing some money at it, but cripes if it doesn't sound like it could totally be used for evil. We're not sure on this one.

Windows for Your Scraper: Media Center in Buick Century [Internal]

Bumbeck's threatening to get on his bad motor scooter and descend down the 110 from the heights of Montrose to check out Gawker Media's new San Pedro facilities. And when we think of Bumbeck, we think of two things (among other things): Sammy Hagar's pre-solo oeuvre and this classic dictum: "I have a theory that every new automotive trend in Oakland starts with somebody inheriting their grandmother's car." Hence the '94 Park Avenues with dubs run sans lowering job, colloquially known in certain 'hoods as "scrapers." Now imagine somebody's grandma in across the Bay in Palo Alto passed away, leaving behind a perfectly serviceable '99 Century in her wake. Read on for the result.

Some technologically inclined nutjob has decided to pimp out his late-model Buick (There are actually late-model Buicks? Who knew?) with the latest in Windows-based mobile entertainment. The Win-MCE-centered system features a 7" touch screen hooked up to a CPU featuring 512MB of RAM, an 80-gig drive, wireless 802.11g networking and a slot-loading, dual-layer DVD burner. Better not park that sucker in Oakland...
