Bikeshares usually don’t have helmets and you have to bring your own.&lt;p&gt;These problems have fixes, but helmet laws generally don’t address them and can just make it easier to drive instead.</text><parent_chain><item><author>bmitc</author><text>I read the abstract and first part of the introduction.

Putting synthetic gasoline in a gas station is essentially an over-the-air upgrade to any conventional ICE vehicle making it guaranteed zero emissions. It’s sort of like carbon offset credits except it bakes the carbon offset directly into the product instead of relying on fragile and game-able links like “we planted a tree to offset this pound of coal”. A potent offering and one that’s hopefully hard to regulate against as well.</text></item></parent_chain></comment><story><title>Georgia’s big new nuclear reactors could be the last built in the US</title><url>https://www.canarymedia.com/articles/nuclear/georgias-big-new-nuclear-reactors-could-be-the-last-built-in-the-us</url></story>
