Sometimes it seems that truth is stranger than fiction. Secretary of Transportation, Ray LaHood, was recently quoted on MSNBC's "Morning Joe" as favoring technology that would block cell phone calls from within automobiles. Specifically, LaHood was quoted as saying, “There’s a lot of technology out there now that can disable phones and we’re looking at that. I think the technology is there and I think you’re going to see the technology become adaptable in automobiles to disable these cell phones. We need to do a lot more if were going to save lives.”
No one will argue that talking or texting while driving is dangerous, but jamming cell phone signals is a bit of an over-reaction. The technology exists, but cell phone jammers are illegal to possess under current laws. As transmitters, such devices would be controlled by the FCC, and not the DOT. Despite LaHood's comments to the contrary, I wouldn't expect cell phone jammers to appear in production vehicles any time soon.
