IMO, there's 2 types of people who use bicycles:
Cyclists
Bike riders
Cyclists don't have a problem wearing a helmet, look after their equipment & obey the road rules.
Bike riders are the types without a helmet, wearing thongs on clapped out clunkers weaving all over the footpath.
In my experience, it didn't affect cyclists one little bit. I did a lot of cycling from around the age of 12 until around my late teens & always wore a helmet. Back then there was only really one type available & it wasn't cheap but it was a no brainer to wear one when riding on the road.
Here's a photo from around 1977/78 on a club day ride through the NSW Southern Highlands. I'm the skinny one in the middle. While helmet use wasn't mandatory, I don't think anyone I rode with didn't wear one.
