Seattle required Pronto (the failed bikeshare system) to have helmet vending machines at the docks, $2.00 per helmet rental. Best information is that about 20% of Pronto users used helmets, most their own helmets.

The dockless bike systems are not required to provide helmet vending machines, because where? Best information is that about 20% of the dockless bike users use helmets, all their own helmets.

BTW, it's still a requirement in Seattle for the brick and mortar bike rental companies to provide helmets as part of the cost of the rental.

Before you say but that just means that they fold the cost of the helmet into the rental, Timbuk2 offers rentals - for free. To make it clear, that's the bike, bike bag, lock, keys, helmet, and map - for free.

And the helmet law still does not have an exception for dockless bike users.
