I agree with Mr Francis Cheng ("Go beyond accident statistics"; Oct 15) that the authorities should not wait until a serious accident happens to a pedestrian as a result of personal mobility devices (PMDs) on footpaths before taking action.

Even a slight, seemingly superficial knock could result in a serious injury to the frail, aged and physically impaired.

My wife, who is near 70 years of age, had hip replacement done on both sides years ago and walks with a heavy limp.

One day, she was walking along the footpath leading to Compass One when a man riding on an electric scooter brushed past her.

She was on the verge of falling, but was fortunately caught by a kind man, who shouted at the scooter rider. The rider ignored them and scooted away.

If my wife had fallen, she could have broken her hips again. Since that incident, she has been afraid of using the footpath alone.

Even with mandatory registration and insurance coverage, it is difficult to identify or detain culprits who hit pedestrians, when they can ride off quickly without stopping.

There should be a close enforcement system, appropriate and practical legislation similar to motor vehicles, or a dedicated lane for PMDs.

We should not be afraid to walk in peace and safety along pedestrian footpaths.
