I have been riding 20 years, scooters, 250s, 600s etc. Even me with 80kg and experience having a 40kg pillion severly limits my movements. With 3 girls on a woeful scooter there is essentially no steering at all except at super low speeds. This will continue to happen until these bikes a confiscated and the adults, cops and everyone who let them do this for as long as they did all share accountability
