It's there to save your life potentially. €299 seems cheap in that regard.

My $50 polystyrene lid does that too.

Regardless, they're not legal in Australia, so even if I wanted to, I couldn't use one.

Yep, helmets are mandatory in Australia for all riders, and the airbag isn't certified as a helmet in Australia.

Are there more, less, or an equal number of bikes around now, after such legislation was passed?

A bunker is also used to potentially save your life, but you don't have one of those either? (I assume)
