We're surprised that this gag can be retailed without disclaimers. CarPool Kenny is an inflatable head and torso that is marketed on the premise that you can cruise the carpool lane in passengerless peace, your inflatable pal offering impunity. People have tried this, and many have had their ruse detected. When you do eventually get hooked by the long arm of the law, it's going cost a lot more than this $20 useless hunk of plastic. Think hundreds.

Your odds of getting caught are likely rather high, since police officers tend to operate on the assumption that all is not what it seems, and Kenny looks so fake that he's just asking to get busted. Our own healthy sense of schadenfreude would kick into overdrive if we cruised by a schmuck whose bluff got called.

Using one of these things to circumvent the rules just means you'll bypass a jam and have to attend to being productive sooner than the rest of us left surfing for that mythical NPR station that's not fund-raising.

Thanks, Jason, for the tip.
