The accident happened in a "national highway" in China, which is not like US highway. There are traffic lights a few miles apart, truck/semi driving at 40-50 mph (sometimes in the left lane). Cars want to move fast would need to maneuver in traffic. I would not be surprised the driver brakes more than 40 times in 30-minute log, if he is a aggresive driver.
He might be an aggressive driver and a frequent braker but not an aggressive braker.
As posted previously,
When the car accelerated to 118 km/hr (74MPH) and only 6 seconds before the collision, the force from the brake pedal was too light: Only 0.3 bar out of 140.7 bar.
That didn't mean it didn't slow down. It did but just a tiny bit: 116 km/hr (72MPH) and it's only 4 seconds before the collision.
He did apply additional force from 4.5 to 12.3 bar (still too light out of 140.7 bar) and resulted in the speed reduction to 94 km/hr (58MPH) just 2 seconds before the collision.
Just about 1 second before the collision, he did apply additional force 92.7 bar) and resulted in the speed reduction to 74 km/hr (45MPH).
Luckily in that split 1 second, the AEB (Automatic Emergency Brake) was helping to get the force of applying the braking pedal to all the way 140.7 bar and resulted in the slow speed of 48.5 km/hr (30MPH).
