In Singapore, three wheels good, two wheels bad.

This was after it was discovered overnight that personal mobility aids (PMAs) -- usually used by the elderly -- are still legal to be operated on footpaths in Singapore, as e-scooters -- defined as a type of personal mobility device (PMD) -- have been banned.

The main difference?

PMAs have a speed limit of 10kmh, and are typically built with three or more wheels that hampers how zippy it can get.

And one company here has even hit upon the innovative idea of modifying PMDs into PMAs for S$449, allowing these devices to continue to be used on footpaths.

What will a PMA food delivery service look like?

Before all these bright ideas sprung out of thin air, a pair of Singaporeans may have already hit upon a method to get around the footpath ban, since their livelihood depended on it.

Given that the hardest hit segment of this ban have been food delivery personnel, a pair of them showed that riding on a PMA-like device can get the job done, albeit being much slower than using a PMD.

This video appeared after Nov. 5, the day when the e-scooter footpath ban kicked in, and before Nov. 9, when the modification of PMAs into PMDs was mooted:

To put 10kmh in perspective: It is the same as running 2.4km in 15 minutes.

Obviously, this pair of food delivery personnel are just playing with their toy car.

Or are they?
