Is there a limit to how much interest lenders can charge people for car loans?

I’m always curious about classic cars, and the 1956 Ford F-100 really piqued my interest. I read that there weren't many of these made and even fewer still exist, but it didn’t talk about figures. How many of these were produced?

I love getting fireworks for the Fourth of July to have my own fireworks show at my house. However, I’ve always had them delivered to my house. This year, I’m going to buy them myself. But is traveling with fireworks in the car safe?

Last year, my car got rear-ended and the other driver paid for the damage through their insurance. When my policy was renewed, my rate had shot up. My agent said this was due to the not-at-fault accident from last year. Why am I being penalized when the accident was the other driver's fault?
