Tesla Inc has introduced several features in its vehicles to help drivers cope with high summer temperatures. These include the ability to cool the car remotely before entering, maintaining cabin temperature when the vehicle is not in use, cabin overheat protection, a 'dog mode' to maintain a set temperature for pets left in the car, and ventilated seats in select Model S and X vehicles. The company also suggests using accessories like sunshades and making weather-specific decisions like mounting summer or all-season tires.
