Tesla General Insurance has updated its personal auto program in Nevada, continuing its shift toward usage-based underwriting rather than a broad rate increase.

The filing was submitted on March 26, 2026 and is under review, with new business targeted for June 1, 2026 and renewals for July 31, 2026. The program now covers 13,490 policyholders and approximately $21.4 million in written premium. While the filing shows a 0.0% overall rate impact, individual changes vary widely, ranging from increases of up to 80.6% to decreases of 26%.

At the core is Tesla’s proprietary rating model, which combines traditional insurance variables with vehicle data and driving behavior. Pricing is driven by factors such as mileage, territory, vehicle characteristics, and a safety score tied to real-time driving performance. Higher scores lead to lower premiums, reinforcing a direct link between behavior and pricing.

The update reflects a shift in how Tesla measures risk. The safety score model moves from version 2.1 to 3.0, replacing forward collision warnings with more granular behavioral inputs such as hard braking, aggressive turning, speeding, late-night driving, and seatbelt usage. The model also shifts from a mileage-based approach to time-based exposure, improving accuracy and reducing opportunities for manipulation.

Tesla is also integrating its driver-assistance technology into pricing. Miles driven using Full Self-Driving are treated as lower risk, lowering premiums and creating a financial incentive to use the feature. This gives Tesla a structural advantage, as no other insurer has access to this level of vehicle-level data.

Another key change is the expansion of mileage bands up to 48,000+ miles. Previously, high-mileage drivers were underpriced relative to their loss experience. This update addresses that gap and improves risk alignment, particularly for frequent drivers and gig economy use cases.

The filing also reduces Cybertruck physical damage rating factors after early loss data showed better-than-expected performance. This helps avoid overpricing and supports retention of a high-value customer segment.

Bottom Line: Tesla is refining risk segmentation using data it uniquely controls—driving behavior and vehicle usage—while keeping overall rates flat to ease regulatory approval. As of December 2024, Tesla reported 7,610 policyholders and $9.8 million in premium; this filing reflects 13,490 policyholders and $21.4 million, signaling rapid growth in both policies and premium.
