A geek who goes by the name of Brandon Fiquett used Siri Proxy to hack Siri for car control. That’s right, he ” managed to get his Acura to communicate with Siri; the Acura has a Viper Smart Start System, which is designed to work with smartphones.” Video after the break.

Fiquett has a custom PHP script that runs on his home server. Some custom plugins are used to augment Siri so it can recognize and respond in specific ways to specific commands. When one of those is sensed, it sends the command to the home server, which in turn spits it out to be recognized by the Viper.
