Why Europe Rejected Japan’s Smallest Cars

I saw a post before about the Subaru 360, the only kei car sold in the US, and how poorly it was recieved. The comparison with the FIat 500 & other small cars was inevitable.

I’ve been digging into kei cars lately and realized something weird:
Japan built an entire ecosystem around them, but Europe – and the rest of the world – basically rejected them.

I made a short documentary-style video on it, but I’m more curious what people here think.
