SINGAPORE: Nur Hidayah Ahssan was walking home recently after dropping off her children at school when a loud thump made her jump onto the grass. A personal mobility aid (PMA) behind her had raced over a metal drain cover.

Soon afterwards, the 28-year-old found herself stopping at a bus stop with her children at the approach of another fast-moving PMA near her son’s school.

Her husband, Muhammad Shareefuddin Malimshah, 28, worries for his family’s safety. “I can’t control the speed of such PMAs or whether my wife is going to be involved in such accidents.”

On any given day in her Chua Chu Kang neighbourhood, Hidayah encounters “at least” five PMAs, many of them travelling at speed.

Her fellow residents will likely find that unsurprising. The bulk of Talking Point viewers who reported speeding PMAs or near misses with them hailed from Chua Chu Kang, Sembawang and Yishun.

In May last year, an inebriated PMA user crashed into a couple on another mobility scooter in Yishun, causing them injuries including a left ankle fracture. The rider, 57, was later sentenced to two weeks in jail.

This July, a 46-year-old woman was surrounded and allegedly attacked by PMA users outside her Sembawang condominium after she asked one of them to slow down.
