"Someone has to make a bold experiment once in a while". This month, we talk to Professor Robert Thomson, Mechanics and Maritime Sciences, Chalmers University of Technology, Gothenburg, Sweden. The discussion begins with PhD work on roadside barriers and ends with a discussion about commitment to grand visions, preventing injuries and saving lives. "Here's what you can do if your government and your society gets on board". The conversation, lead by Editor-in-Chief of Injury Prevention Rod McClure, also covers the unintended safety costs of electrification of modern vehicles. There remains a world of opportunity for the safety engineer.
