Autoweek in review: What you may have missed

Rain fell all week at One Autoweek Tower, and the breaking news didn't let up, either. Things started out busy enough on Monday with Bugatti losing its top-speed record and the trailer of Ron Howard's new film, “Rush,” hitting the Web. On Tuesday we paid homage to Distracted Driving month by recounting the touching story of a Kansas State Trooper who has witnessed a variety of tragic scenes -- many resulting from distracted driving.

MIT develops self-transforming materials that behave 'like robots without robots'

A cross-disciplinary research lab at the Massachusetts Institute of Technology (MIT) has developed a suite of programmable materials, including carbon fiber, printed wood grain, textile composites, rubbers and plastics, that self-transform when exposed to an external stimulus. Director of the Self-Assembly Lab, Skylar Tibbits, presented a TED talk on 4D printing in 2013, where he demonstrated how a flat sheet of material could effectively build itself when exposed to water, like a robot without a robot. Following positive feedback from industries including aviation, automotive and manufacturing, his lab has been working on developing materials that change according to different activation sources, including heat, light, and air pressure, in addition to water – all of which have automotive relevance.

Call for reform over road repair funding

FUNDING patterns mean most road maintenance is being carried out in "less-efficient, cold and wet" times, a report from a Government spending watchdog has said. The current pattern of funding, combined with the need to spend money within the financial year, means that most maintenance work goes on between September and March, said the report from the National Audit Office (NAO). It went on: "Although this is less disruptive for road users, it is less efficient than carrying out the work at other times of year because materials can be more difficult to handle in cold and wet conditions, and daylight hours are shorter." The report went on: "As a result of the additional funding for emergency repairs, which is made available at the end of the financial year, almost all highways authorities need extra capacity from the market at the same time, which makes it less likely that they will get value for money." The NAO report said there was a "lack of predictability" over road spending adding that historically, local highway authorities spent more revenue on maintenance, but were now carrying out fewer routine activities such as clearing gullies which are essential to preventing water seeping into roads' sub-structure.
