Half-shell helmets still feel unsafe during accidents

Today on the road, there was a motorcycle in front of me. It seems like it slipped on a manhole cover after hitting some water when braking. It slid and crashed into the motorcycle in front of it, and then they both hit a third motorcycle. The rider of the second motorcycle wasn't wearing their helmet properly. The half-shell helmet slid right onto the road, and a car ran over and destroyed the helmet. Thankfully, the person didn't slide along with it, otherwise, we might have seen a watermelon-smashing scene right there. So, always buckle up your helmet when riding, and if your tires are worn out, replace them soon.
