Tesla does the battery
Tesla does the battery cooling the superior but more expensive way... It’s worth informing people about these differences if they’re unaware. But yeah - bottom line is you couldn’t buy a Leaf or an electric Smart4Two or other cars like them at the price points they’re at otherwise. If they’ll cover failing batteries under a decent warranty and they’re not as costly a battery as a huge Tesla battery (hint: they’re not)? It may not matter much. Pay for battery swaps if and when needed and you’ll still be better off cost-wise than having paid a lot more for the car.
