Tesla yesterday rolled out an insurance line for vehicles in California and plans to eventually expand it to other states.

Why it matters: The electric automaker said it's "designed to provide Tesla owners with up to 20% lower rates, and in some cases as much as 30%," adding that it "reflects the benefits of Tesla's active safety and advanced driver assistance features that come standard on all new Tesla vehicles."

Pew Research Center data shows that public concern about climate change has risen over the last 6 years — but the angst isn't exactly shared across political lines.

President Trump has approved an emergency declaration for Puerto Rico to enable federal assistance, with Tropical Storm Dorian fast approaching and the U.S. territory on hurricane watch — as forecasters warn it could take a direct hit Wednesday.

Why it matters: Puerto Rico is struggling to recover from Hurricane Maria. It declared bankruptcy in 2017 amid "the biggest government financial collapse in United States history." Puerto Rico Gov. Wanda Vázquez Garced has already signed an executive order declaring a state of emergency on the island, per Bloomberg's Michael Deibert.
