Pity no one mowed that rodent down.
Looks like an excellent way to get around. PMDs take up very little space which leaves more room for other vehicles. They are fast so they don't hold up traffic the way cyclists do.
However most importantly they facilitate social distancing. If that PMD rider is infected with the coronavirus chances of him passing it to others during his trip is very, very low.
If he took the MRT though the whole carriage could end up with Covid-19.
This is why we need more PMDs and less cars especially during these trying times.
