Nearly $4 million in cars piled up Sunday in Japan when eight Ferraris, three Mercedes, and a Lamborghini crashed on a wet highway. A pack of 20 supercars were traveling when the lead Ferrari hit the median guardrail; the cars behind it were then unable to brake in time. Fourteen cars ended up crashing, including two Toyotas. The cars were speeding, according to police, and 10 people sustained minor injuries.
