Singapore Public Transport is obscenely overpriced (compared to equivalent PMD use). PMD (personal mobility device) (e-scooter) with 40Ah battery @25V motor is 1kwh/battery charge =24cents electricity from PUB. (Household electricity tariff today is SGD 24cents/kWh). This 1kwh/ battery charge can travel up to 60km distance @25kph (LTA speed limit). Average public bus speed is only 17-18kph (see quote below). @24cents/60km is less than half cents per km distance travel. What public transport mode can beat this PMD transport mode price? Returning to 'suicide' topic (parent thread discussing elderly suicides in Singapore) more people will commit suicide as they are being ripped of by high public transport prices simply because technology is available to provide public transport @ under half cents/km travelled: yet the government selfishly prevents its implementation /use. And PMDs are much more energy efficient (lighter, no frills)... That is why the bus model is OBSOLETE because it is pollutive and clumsy (restricted routes, unpredictable traffic delays, crowded) and has restricted operating hours. PMDs are the way to go and the technology is now ready and ripe to use for journeys under 40km in Singapore / other cosmopolitan cities.
