"83% of Americans connect Musk with Tesla and that's a problem for Tesla considering that Musk’s reputation is much weaker than Tesla’s," Shahar Silbershatz, CEO of stakeholder intelligence firm Caliber, said, adding that it has seen a decline both in the reputation and the consideration rates for Tesla since Musk has acquired X, formerly Twitter, more than a year ago.

Tesla's Model Y and Model 3 were the top selling light truck and sedan in California for the year, respectively, by wide margins.
Consumers in California have been gravitating towards less expensive hybrid vehicles, which can run on gasoline and electric power.
Market share of vehicles with that powertrain type in California jumped to 13.3% in the fourth quarter, compared with 8.7% a year earlier.
The market share of battery electric vehicles in the state also fell to 21.1% in the fourth quarter from 22.3% in the prior three month period.
