While Toyota already has its self-parking Prius on the streets, and Volkswagen (not to mention BMW and Honda) isn't too far behind, Citroën is joining the fold thanks to a newly-unveiled system developed by Bosch. Citing the C4 Picasso as the "world's first car to feature integrated parking space measurement," Bosch apparently hopes to get its own snazzy parking assistant on more rides in the future. The system utilizes six total sensors on the front / rear of the vehicle to gauge parking space dimesntions (and alert you of obstacles) while cruising by at up to 12.5-miles per hour, and can inform the driver if the space he / she is eying is too small, "a tight squeeze," or just right. The system initiates the measuring process when the motorist tags a button on their steering wheel, and looks to the right or left depending on which turn signal is in use. While not quite as advanced as Toyota's gig, Bosch hopes to upgrade its system to allow the vehicle itself to control the maneuvering sometime in 2008, but those not able to hold out can pick up the current rendition real soon.
