This video discusses the solution to traffic congestions on a global scale: smaller vehicles.

The number of vehicles globally will double between 1990 and 2025 while the length of commonly used road in cities remains largely the same. Traffic congestions increases the unpredictability of traffic conditions and travel time, increasing the amount of non-productive time. Taking a cue from the maneuverability from motorcycles but with safety in mind, smaller and safer vehicles may address the problem of limited infrastructure falling behind growth of vehicles.

However, even though smaller vehicles can bring a partial relief to congested roads, some questions remain to be answered before deciding if it can be a long term solution. For example the energy efficiency of the vehicles compared to other modes of transport (i.e. public transports) should be considered. If the vehicles are inherently the less energy efficient mode of transport, can developing intracity infrastructures to support such form of transportation still be a sustainable long term solution?
