The Environmental Transport Association (ETA) is a British carbon-neutral provider of vehicle breakdown, bicycle and travel insurance for the environmentally concerned consumer. The ETA aims to raise awareness of the impact that transport has on the environment and help individuals and organizations to make positive changes in their travel habits. They offer breakdown and road rescue for cyclists, mobility scooter users and motorists. In 2015, the ETA was voted Britain's most ethical insurance company by the Good Shopping Guide. Promotional vehicles The ETA has built a number of unusual vehicles over recent years to promote sustainable transport as well as its own insurance products, two of which gained Guinness World Records. The Guinness World Record for QTvan is a tiny caravan designed to be towed behind a bicycle or mobility scooter and is officially recognized as the world's smallest caravan. The Hornster was designed and built as a way of highlighting the danger posed to cyclists by lorries in urban areas. The bike is fitted with the air horn from a freight train, which is powered by a SCUBA diving cylinder, and has been judged by Guinness World Records to be the world's loudest bicycle horn. The BOND bike was built by the ETA is response to the frustrations faced by urban cyclists; it features a handlebar-mounted flamethrower to dissuade motorists from overtaking too close, a caterpillar track to negotiate potholes and an ejector seat to deal with bike thieves.
