I believe the totaling threshold for CA is "salvage value + repair costs >= actual cash value". My advice is on the assumption you are working directly with Farmers (i.e. you have not filed a collision claim with your own insurance, and the other driver's insurance has accepted liability). Remind the adjuster you will be seeking a Tesla rental during the time of repairs. The last time I quoted such a rental, it was $1800 a week. Remind the adjuster, given the backlog of repairs and availability of parts, scope of the damages, repairs will likely take 20 weeks or more, so rental costs become $36k+. Remind the adjuster you will be seeking diminished value, which for a vehicle with airbags deployed, will be on the order of 20-30% of actual cash value. If the adjuster isn't swayed to the "totaled" side of the equation yet, maybe remind him you are already seeking lawyers to help with the diminished value and loss of use (if they don't provide a Tesla rental immediately) tort claims. Good luck.
