Helmet legislation in Canada has resulted in higher helmet use, so this cannot explain the results.
The current study explored whether a High-Tech-VR helmet (ie, a 60-degree field-of-view head-mounted display) reduces pain more effectively than a Low-Tech-VR helmet (a 35-degree field-of-view head-mounted display).
However, a high-tech bike helmet would fit nicely within the Contreras's company interests, and it makes sense the two would want to see the helmet through to production.
