Welcome back to the Nerd Alert podcast! This week we have a deep dive episode about something that’ll likely bring positive change to the helmets we all wear. Our guest is Peter Haldin, the Chief Science Officer and a Co-Founder of MIPS. However, in this interview, Peter is wearing another hat (helmet?) and speaks about his role as the Convener of the Working Group 11 (WG11). In short, WG11 is working to bring rotational-based testing to helmet safety standards, and the goal is to help reduce the number of brain injuries suffered from cycling crashes. Where things get a little confusing is that the likes of Rudy Project and Kask have already started promoting that their helmets meet WG11 test standards. This episode clarifies what this working group is, what the testing involves, and what the future of helmet safety may look like.
