This is nearly a perfect device. If only you could record your own message – something situationally appropriate, perhaps. As it is, Our Lady of the Trunk is the perfect companion when you're preparing to worship at the feet of Our Blessed Mother of Acceleration. Most of us will have to back out of our driveways or parking spots before summoning full ahead from the propulsion plant, so offertory to these spiritual matriarchs could be considered part of the religion of driving. Really what this little doohickey amounts to is a reversing alarm, but it's apparently got a voice sample in its electronics, along with the standard klaxon. You couldn't pay a loudmouth to hang out on your bumper and announce with the authority of a 100dB sound pressure level that the vehicle is backing up, so how can you go wrong for less than ten bucks? The voice is only in English (sorry, rest of the world), but in the box are the requisite transducer and its power leads, a bracket, and instructions in three, count 'em three, different mother tongues. Father's day is coming up!

In a move sure to please more than a few motorists, police in Tulsa, OK are testing new sirens on their patrol cars with a tone low enough to send vibrations through targeted vehicles and their occupants. It sounds strange, but as cars become more isolated from the outside world, it has become increasingly difficult for cops to grab the attention of wayward motorists. Locked in our motorized cocoons, a wailing siren just can't be heard over the din of cell phones, Sponge Bob and iPods.
This new and innovative (and non-sadistic) approach called the Rumbler is designed to blast a deep tone up to 70 yards away to alert drivers through vibrations in their backsides. The Tulsa police have three units in use, with three more expected within the next ten days. Law enforcement officials in Washington DC, New York, Pennsylvania and Florida are also trying the technology. Talk from the officers and the public indicates this apparently harmless approach works pretty well. If put into widespread use, it seems to us that the booty-shaking siren just could become the best part of being pulled over.
