Recently, a news about the heating of the rear seats of Tesla Model 3 has attracted the attention of the public. According to reports, Tesla officially launched the Model 3 rear seat heating function. There is no need to add hardware. It only needs an online OTA upgrade to unlock it. It costs US$300 (approximately RMB 2,000). In other words, Tesla Model 3 cars are already equipped with a rear seat heating function when they leave the factory. Consumers have paid for this part of the hardware, but Tesla has used software to block this function. Tesla's charging strategy quickly caused dissatisfaction among netizens. It is worth mentioning that this strategy was also very common in the game industry, the so-called game DLC (downloadable content). Capcom, a famous Japanese action game developer, was once dug out by netizens in the first release disc of "Resident Evil 6" that already contains the maps and characters of the subsequent DLC, but it requires players to pay for the unlocking key that is only a few MB in size. The players unanimously resisted. Some netizens ridiculed that Tesla should learn from the free strategy that is currently prevailing in the game circle. Model 3 cars are free and all functions are shielded. Consumers pay to "draw cards" or "out of the box". The more practical functions are provided, the lower the price. The explosion rate, "redefining the car." Of course, compared to mobile games where the cost of acquiring new users is almost zero, it is impossible for Tesla Model 3 cars to "deliver for free". The ridicule of the "soft unlocking" of heated rear seats is more of a show Consumers are dissatisfied with Tesla's introduction of bad ethos into the auto industry. As of press time, Tesla has still not responded to public doubts.
