Tesla registrations rose by 11.8% in California in Q2. Things got pretty ugly for Tesla early last year, when the backlash to Elon Musk's involvement in the Trump administration hit fever pitch. Tesla sales dropped around that time across the globe, and in the EV stronghold of California, too. But it's progress, and Tesla is doing far better in California than it is in the rest of the country. EV registrations in the state also showed signs of a serious rebound by jumping 40% as compared with Q1.
