Connecting to unsecured Bluetooth car systems to monitor traffic flow.

TheTerseOne writes: The Columbian, the local newspaper of Vancouver (not BC), Washington (not DC) is reporting that local country traffic officials plan on spending $540k of government money to monitor traffic by connecting to vehicles whose owners/drivers have left their Bluetooth car systems 'discoverable.' The county claims that, although this sounds "creepy" and "like big brother" there is no cause for concern. The specific brand of the system is not mentioned, but similar systems have already been the subject of security alerts.
