I wouldn't worry too much about this.
Once early Tesla Model S's began to accumulate mileage, it began to become apparent that engineering projections about battery life had been far too conservative. One of the early signs was the Amsterdam Airport taxi fleet that ran Teslas 24 hours a day and constantly charged them fully at DC charging stations -- practices that tend to stress the batteries most. As those cars began to pass the 200,000km mark on their odometers with relatively little loss in charging capacity, optimism grew that li-ion batteries with good battery management systems would be considerably more durable than predicted.
As data has continued to come in, studies are now finding that car batteries with good management systems (such as Tesla's and Lucid's) are likely to last the life of the rest of the car. There is a minor decline in charging capacity that occurs in the first months of use, but the degradation curve then significantly flattens, and several years out the battery packs seem to be stabilizing in the range of 7-8% loss in charge capacity.
Will they eventually wear out? Yes . . . but probably long before most owners have moved on to another vehicle.
In fact, Lucid, Tesla, and other car companies are already developing plans to redeploy battery packs from retired cars to energy storage use by power utilities.
