The article never defines what a "risky" driving behavior is. Is accelerating quickly risky? Is cornering at less than 10 under the speed limit risky? The answer is "maybe." It all depends on the car and driver. A sports car with a sport suspension with sport tires makes doing these things safer than if you're driving a Jeep Wranger with off-road tires. There is no single definition of "safe." It all depends on who, what, and where.
