Mr Tan Kim Hock's statement that the Land Transport Authority seems to be adopting a laissez-faire approach towards shared bicycles, personal mobility devices and electric scooters has some merit (PMD regulations are better late than never; March 13).

This same approach has been adopted towards private-hire car companies like Uber and Grab too.

The best way to curb congestion is to cut down on the growing car population. However, the number of private-hire cars stands at about 47,000 now (Licensing Grab, Uber may curb car population; March 13).

This is a staggering figure and is likely to increase, if not curtailed.

It seems as though LTA is not adopting a proactive approach towards this issue.

For example, LTA usually studies areas with high levels of congestion and erects Electronic Road Pricing gantries in these places.

However, the growing population of private-hire cars have added to the congestion on the roads, and if LTA had restricted the number of such cars on our roads, there would be no need for more ERP gantries.

It bodes well for LTA to have the foresight to anticipate all the problems that come with the invasion of thousands of these extra vehicles on our limited roads, and act now.
