I know all that. and genuinely feel bad for you guys.Welcome to Australia...
.
Spanish Helmet law is my favourite.
In Spain we're going to make wearing a helmets compulsory for all riding of bicycles outside of towns!.
Ok, but what about when it's too hot ?
Well.. .not then obviously
Ok. so what about climbing up a big hill?
Well... no... not then either.
Ok.. so what about kids?
yes. they should always wear helmets.
What? even for short journeys?
Well.. .no not then.
In reality if a spanish cop stops you. They'll ask why you're not wearing a helmet, and listen to your answer. then say something along the lines of "you probably should wear one" and off they'll go.
Having said all that spanish drivers are among the most courteous towards cyclists I have ever encountered
