I’m also talking about small cars in general over just kei cars—minicars. There is a number of cool kei cars below, and I’ve mentioned some mini cars already. The government could incentivize people to buy mini-EVs too with tax rebates in the same way Japan incentivizes kei cars. Cheaper cars usually get a break on registration fees and insurance, but the government could do more.
