Your method sounds like a good way to inject noise into the system -- and perhaps it is. Except the article describes integrating this MAC-sniffing business into ALPR camera installations. In this way: You drive by with your noisemaking-device, and it records that noise along with the presence of your license plate. It won't take a senior data analyst to correlate the bursts of noise with your proximity. Instead, you'll stand out like a sore thumb and they'll see you coming even before they have optical line-of-sight. (It could scale, but as a practical matter it simply won't. Most people aren't interested in this kind of obfuscation; it'd be amazing to me if even 1/10,000 people were to actually adopt it. This level of rarity would identify you as one of the 0.01% of troublemakers.)
