Finally something sensible from this guy. Last week it was all big auto lobby nonsense.

They are actually locked. In the Netherlands bikes usually have ring locks attached to the frame that lock just the rear wheel. It’s way more convenient, you can quickly lock your bike and pop into a store. It’s of course less safe, so especially in larger cities and at train stations people do lock their bike to something.

To everyone who is saying they use adblock and haven’t seen this yet: YouTube probably rolled this out to a smaller percentage of users first. It allows them to understand how this change impacts user behaviour, e.g. how many users comply and disable their adblocker, how many more users close YouTube than usual etc. Most tech companies do this type of analysis before releasing a high impact change to all users.
