TOKYO (AP) — An outing of luxury sportscar enthusiasts in Japan ended in an expensive freeway pileup — smashing a stunning eight Ferraris, a Lamborghini and two Mercedes.

Police say they believe the accident Sunday was touched off when the driver of one of the Ferraris tried to change lanes and hit the median barrier. He spun across the freeway, and

the other cars collided while trying to avoid hitting his car.

Video of the crash aired by NTV, a major national network, showed several smashed, bright red Ferraris cluttering the freeway.

No one was seriously injured, but police in Yamaguchi prefecture said 10 people were treated for bruises and cuts. Police say 14 cars were involved altogether.

The luxury cars were all in one place because they were being driven by a group of automobile enthusiasts on their way to nearby Hiroshima.

“The accident occurred when the driver of a red Ferrari was switching from the right lane to the left and skidded,” said Mitsuyoshi Isejima, executive officer for Yamaguchi Prefecture’s Expressway Traffic Police unit. “It was a gathering of narcissists.” The drivers were aged between 37 and 60 years old, he said.

The person suspected of causing the accident, a 60-year-old self-employed man from Fukuoka prefecture, may face up to three months in jail or a fine of as much as 100,000 yen ($1,280), said Isejima.
