Rumble strips are dangerous

Alone cycling home with about a 1klm to go. In the cycling lane preparing to enter the traffic lane to be able to take 2nd exit at the roundabout ahead. Left hand on handbars, right hand assisting in looking behind me for on coming traffic. As you will see, I drifted in the cycle lane towards the rumble strips. As I started to look forward again and take control of the handle bars, the bike started to contact the rumble strips and caused me to not be able to regain control of the handbars, which resulted in the crash. Injuries include; cracked lower ribs, dislocated collar bone (ACJ), damaged tendons and some bruising to the body, arms and legs.
Thanks to all drivers who stopped to assist and the emergency services.
