@darrelld . Has the Tesla approved shop done a detailed repair estimate? We had our Model S hit in Feb. Initial visual estimate was $16.5K so the insurance was not even thinking about totaling (as they should btw, I don't blame then given the information they were provided). 3 weeks later (today I hear the wait is much, much longer around here), after the shop finally got to disassembly and detailed estimate, they stopped at $65K of estimates to check with the insurance whether they should keep on going (it was a barely 1 year old MS so they had no threshold in their computers). At that point the insurance company declared it a loss. 2 months later we got a new Model S. My wife walked away from the accident by the way, though with some pains and bruises which lasted for few weeks.
Btw, not sure what your insurance covers but ours maxed out at $1,000 of rentals. I checked after the accident whether I could increase that limit for the future, but State Farm said they don't offer any higher insurance for car rentals. Maybe if it wasn't for the fact that we were hit but an uninsured motorist who fled the scene and was never found, maybe they we could have sued for more car rental reimbursement.
Here is the accident and damage done to the car for comparison; your car looks more damaged though ours was at higher speed. The video came really handy proving accident fault - without it it would have been impossible whose fault it was (similar outcome if our car were to cross into the left lane) and without the other driver it would have been a different claim. The deductible difference itself covered the cost of dashcams in both of our Tesla's - that's why I install dashcams front and back on all our cars, then hope to never have to use them.
