A while ago, it was announced that the authorities were dealing with shared bikes that were left indiscriminately at road junctions, street corners and bus stops.

The process, as I understand it, starts with Land Transport Authority officers spotting the bikes and making calls to the respective operators.

If the bikes are not collected within a certain period, they will be impounded.

The whole process requires patrolling, informing, monitoring and physically removing the bikes. This consumes much time and manpower.

Who is paying for these extra activities the authorities are forced to engage in?

I could not agree more with Mr Cheng Shoong Tat's suggestion to tax the bikes (Impose a tax on every commercial shared bike; Oct 20).

The cost may be passed on to the users, but if this means that users will become more conscientious and responsible, then so be it.

Many people do not use bike-sharing services. Taxpayer money should not be used to clean up the mess across the island made by users of shared bikes.
