Wearing a helmet will become compulsory for under 16's in the UK. I've
read/heard many people complaining that this will deter people from picking
up cycling, as wearing a helmet implies a dangerous activity.

I totally disagree with this.

What do you guys think?

Read a few of the previous articles. They're all on Google newsgroups.
And it's "might" become compulsory, not "will".
