Yesterday, President Obama gave a speech in Virginia calling for mandatory installation of vehicle-to-vehicle and vehicle-to-infrastructure communications in all cars. By coincidence, the Association for Unmanned Vehicle Systems International (AUVSI) is holding its annual symposium on autonomous (that is, driverless) cars in California.
V2V allows vehicles to communicate with one another to allow them to avoid accidents, while V2I allows highway infrastructure (such as traffic signals) to communicate directly with motor vehicles. While Obama touts the safety benefits of these technologies, there are at least four reasons why they should not be mandatory.
First, V2V and V2I communications pose serious security risks for travelers and cities. With V2V communications, an automobile that suffers a fender-bender would communicate to all nearby vehicles that they ought to take a different route to avoid congestion.
