I have Tesla Insurance - and have had it for most of the past 3 years with my Model 3. It's great. It's not a special app - in fact it's not even a special website; it's kinda sloppily glued-on to the main account site with Tesla. It's just insurance: looks, acts, tastes, smells like insurance, down to claims and everything (they provide Enterprise rentals... which... doesn't include renting a Tesla or any other plug-in hybrid or EV. So I had to find a rental elsewhere, which they didn't cover, lol).
There's not been any buzz yet about implementing this stuff or customizing plans to driving habits. Tesla Insurance has been totally quiet.
