What influenced you to start wearing one?
Price decrease
Increase in choice
Varying styles (e.g. shape, graphics, materials and textures)
Increased comfort (e.g. weight and fit)
Increase in availability
More people were wearing them
Encouraged to by others (friends/ family)
Influenced by professionals in media/film
Regulations in the area
An injury to the head
An injury to a friend or family members head
To set a good example to others
Nope, this question is definitely flawed as it deals with actual injury in the past rather than the potential for, or fear of injury in the future. I think this effectively excludes many people who wear helmets. I appreciate you are focussing on design, but if your data collection doesn't properly address the reasons for helmet wearing, the solutions you provide will be incomplete.
