This happened in Louisiana with auto insurance.
Years ago, there was an idea floated that each car owner, paid insurance only for their car. Want to drive a $100,000 EV, get in a wreck & your policy covers your losses, injuries etc. and if the other driver doesn’t have insurance, they’re SOL.
Today, someone owns a $100k EV, gets a scratch and totals it, their experience gets co-mingled with your $25k car. This way, cost is based on car type, claim history etc. and your underwriting these costs.
