Some state they may charge you more, however. I just looked up a few:
State Farm: "Drive Safe & Save is always a discount and does not surcharge your policy. The Drive Safe & Save discount is based on your annual mileage and basic driving characteristics."
Nationwide: "Can SmartRide increase my premium? No. This is a discount program. SmartRide measures driving behavior to reward you with a discount, not raise your rates."
Allstate: "Customers will receive a policy discount for participating in Drivewise and those who sign up and avoid risky behaviors can save on their premium. If customers stay active in Drivewise (active participation means at least one driver takes 50 trips or drives prior to renewal processing), their participation discount will not decline, but overall premium savings from Drivewise will depend on the customer's driving behaviors. Drivers who have riskier driving behaviors are expected to see a higher price from participating in Drivewise."
GEICO: "DriveEasy is a new program that promotes safe driving by providing both GEICO and the customer valuable information about individual driving patterns. This is designed to help you become a safer driver. Most customers will be able to save based on their safe driving habits, however riskier drivers may see a higher rate – depending on the state you live in."
But the law is, auto insurance companies can only make money on scale. If they charge premiums that are out of line for the risk being covered they have to refund them. This happened when people drove significantly less during covid.
