You could be at risk of being pilfered by officialdom anytime you sit behind a steering wheel. Between 2001 and 2014, lawmen seized more than $2.5 billion in cash from sixty thousand travelers on the nation's highways—with no criminal charges in most cases, according to the Washington Post. Federal, state, and local law enforcement have institutionalized shakedowns on the nation's highways to the point that "forfeiture corridors are the new speed traps," as Mother Jones observed.

Police can almost always find an excuse to pull someone over. Gerald Arenberg, executive director of the National Association of Chiefs of Police, told me in a 1996 interview, "We have so damn many laws, you can't drive the streets without breaking the law." The Washington Post reported that police set up "rolling checkpoints on busy highways and pulled over motorists for minor violations, such as following too closely or improper signaling," and "looked for supposed 'indicators' of criminal activity, which can include such things as trash on the floor of a vehicle, or abundant energy drinks."
