$XIAOMI-W(01810.HK) Lei Jun's biggest mistake was making electric vehicles. EVs have brought convenience and experience to the vast majority of people, but if the company cannot guarantee that the battery won't violently combust and cause fatalities in the one-in-ten-thousand accident scenario, then this company is an unscrupulous enterprise, and its leader is a businessman without conscience. No amount of showmanship can cover up this simple truth that even ordinary people understand. There are so many fields where Lei Jun and his company could steadily work to benefit ordinary people (like sanitary pads), yet they insist on diving into this unscrupulous and unpromising EV industry.
