如今的汽车远比当年的T型车（福特Model T）要复杂，全球供应链很容易受到不可抗力的影响。
与 Model T（当年的处境）相似，电动汽车的电池产业规模还不够大，因此，电池供应链必须同步构建才好。
有好的想法很容易，但要把这些想法落地实践并不容易。

Cars today are far more complex than Model T, with a global supply chain that is vulnerable to force majeure risk.
Like Model T, supply chain for battery EVs simply doesn't exist at massive scale, so must be built in parallel.
Ideas are easy, production is hard.
