Not in CA. You can enter your existing policy. Most insurers in CA grant a10 day grace period to add your vehicle on your insurance. I've added my insurance info since I'm retaining my existing policy for my P3D whenever it arrives.
Edit: Unless you don't own a vehicle now or do not have an insurance policy already. If through Tesla insurance, yeah, I think you have to wait for a VIN.
Screw it. I'll just upload my insurance to satisfy them. Then when the VIN is assigned I'll grab a quote
I went ahead and added my insurance as well. But no image shows in the little box? Same for you?
