Tesla, the car company run by Elon Musk, reported Wednesday that it sold more vehicles in the past three months after boycotts hit hard earlier this year, but profits still fell sharply. Third-quarter earnings at Tesla fell to $1.4 billion, from $2.2 billion a year earlier. Excluding charges, per share profit of 50 cents came in below analysts’ estimate. Tesla shares fell 3% in after-hours trading. Musk said the company’s robotaxi service, which is available in Austin, Texas, and San Francisco, will roll out to as many as 10 other metro areas by the end of the year.
