With narrow tires, small brakes, loose chassis, and no ABS, old cars aren't the safest things in an emergency situation. The occupants of two Australian cars found this out the hard way, as one classic skidded into the path of another.
On a classic car tour in southern Australia, a 1970s Ford Falcon XY GT locked up while panic-braking for a slow car ahead. That send the Ford across the center line and into the path of a 1960s Holden EK sedan. The crash knocked the Holden clear off the road, as the older car's dash cam video shows.
