Tesla is jumping into the auto insurance industry with some ambitious plans.

Tesla reported on Wednesday that they will be launching a new insurance plan for their electric vehicles. They’ve promised electric vehicle owners that this new plan would save them at least 20% on insurance, with a possibility of savings as high as 30%. For the time being this new plan, Tesla Insurance, will only be available to drivers in California. While Tesla didn’t name other states or provide a timeline, the plan should be made available in other US states in the future.

This announcement follows an announcement in April by Tesla CEO Elon Musk, where he revealed that the company would be launching an insurance plan. When he announced the plan, he said that it would be “much more compelling than anything else out there.” The idea is that Tesla will be able to leverage the costs of offering such an insurance plan through “advanced technology, safety, and serviceability of our cars.”

As would be expected with any insurance offer, Tesla explained that the specific cost of their insurance will vary depending on each individual’s driving record and the typical factors considered for an insurance rate. The company also promised that it wouldn’t use or record GPS history, camera footage, or any of the metrics that Tesla vehicles are capable of recording in the decision-making process. However, the company did say that it would use anonymous data from their global fleet to help them determine the rates they’ll be offering.
