The Tesla Insurance was easy to get (naturally since it is their company). The premium varies each month based on the miles driven and your safety score. The safety score is determined by how much you drive over 85 mph, how close you drive to the vehicle in front of you, how fast you take corners, heavy braking, and the time of day you drive. Biggest hit to the score is driving after 10pm and before 4am, from what I remember in 2023.
Edit: Looks like they revised the score system some since I had it
