The Double-Wide (Also Dee-Dub, Double, Dubby, or DW) is a vehicle that came to prominence in the United States in the mid- to late-21st century. As its name implies, the DW is just over twice as wide as a standard vehicle. It occupies two lanes in a street, and generally sits much higher than a standard vehicle. DWs are considered one of the focal points and originating factors in Toofers. 

Origins

Historians and Anthropologists note contributions from various sectors that led to the rise of the Double-Wide.

Commercial Interests

The DW was promoted with advertising, lobbying, and corporate subterfuge by the combined interests of the Petroleum, Auto-making, Real Estate, Engineering and Civil Contracting industries, among others. Its widespread adoption meant a bonanza for industries that built, fueled, or laid concrete for it.

Consumers

Near the mid-21st century, Anti-Environmentalist Culture had reached a fever pitch for its adherents, who often made major material sacrifices and adjustments to their lifestyle to make their beliefs clear. As Electric Vehicles had increasingly become standard in the developed world, their reaction was to double-down on their commitment to the internal combustion engine. It became a point of pride to own a double-wide, even if they were not yet street-legal in that jurisdiction. As DWs became more commonplace, they went from a mostly rural status symbol to a common sight in city centers redesigned to accommodate them.

Government & Regulatory Bodies

Main Article: The McDoubling

The United States underwent a sweeping pattern of amendments to civil engineering codes, zoning regulations and civil tort laws, accompanied by enormous expenditures to retrofit its infrastructure to accommodate DWs. This was known as The McDoubling, often cited as a factor in that society's collapse.

Many jurisdictions moved to legalize DWs for consumer use in all roadways, often ahead of any indicated consumer demand. DWs were afforded special privileges and exemptions in traffic rules, such as designated lanes, mandatory right-of-way, collision liability exemptions, and pass-under obligations for smaller vehicles. 

Some jurisdictions banned DWs outright, the smallest of which simply got Raze Rallied. Others were subject to various angles of sabotage by the various private interests and aligned governmental actors that stood to profit.

The Double-Wide was an explicit strategy in the Climate Conspiracy.

Description

DWs are often widened versions of existing standard-sized SUVs and pickup trucks, with seating for four to twelve people per row. Some models have two stories, with the driver's seat most often being located on the second story. The interiors are fitted as mobile homes, businesses, vacant passenger seating, or any other justification for using this much space.

The largest models retain the conventional four-wheeled design, with enough space underneath for a single standard vehicle to pass in a parallel or lateral direction. In most jurisdictions, those passing such a DW are legally obligated to pass under the vehicle rather than around it - because it's important to utilize space efficiently, folks!
