While there are already some Kei cars in the US, they are a rare sight and have to be at least 25 years old to run legally on American roads.
Business accounts manager Nevi Bergeron bought her turbo-charged yellow 1997 Suzuki Cappuccino three years ago after being inspired by the Japanese street racing manga series Initial D.
Like most Kei cars, it is so small that two can fit into a standard parking space.
“I fell in love with that car and instantly knew I had to get one,” said Bergeron, a member of a local enthusiasts group from Maryland and Washington DC called the Capital Kei Car Club.
“It’s tiny and a bit silly… definitely a conversation-starter. You get a lot of glances when you drive around the city,” she said. “I just feel so happy in it.”
But despite loving the petite coupe, she wouldn’t recommend it as a daily runaround.
“It is fun to drive but it is not exactly what I’d call safe,” Bergeron said. “On a highway next to big trucks, you definitely feel vulnerable.”
For the same reason, Capital Kei Car Club founder Andrew Maxon drives his Autozam az-1 mini-coupe “like a motorbike” – always assuming that other vehicles, especially trucks, have not seen him.
US transport secretary Sean Duffy said as much, acknowledging that small cars would “probably not” be well-suited to American freeways.
But these cars could be a “great solution” for people who drive in cities, Duffy said on business news channel CNBC.
