A plausible issue I can think of is that installing charging infrastructure for every parking lot would be tricky. The range of electric cars is probably only just about enough for one end of Singapore to the other, back and forth.
Say about 80 miles, that's about 128km, on optimistic ratings. Add in traffic jams, overtaking manuevers, random hazard avoidance, say you cover 30km each way everyday, most electric cars should be able to tahan a day's worth of driving.
But then, when you come home, likely must charge your car if you intend to use it the next day without fear of running out.
If entire residence all using electric cars, it means every parking lot must have a charger. And unlike refueling liquid gasoline/diesel, electric charging takes much longer, probably at least an hour, even with "supercharging" technology.
And if everyone is charging their cars at the same time, this is still a lot of kilowatts being consumed off the grid. A lot of load placed on the grid.
But combined with alternative technologies such as solar panels in our crazy hot weather, maybe more sustainable than fossil fuels.
But I have a feeling that the contractors or govt. just aren't willing to invest heavily in the necessary infrastructure to make electric-only vehicles viable for the masses.
Otherwise, if we go mass-market electric without the appropriate quantity of chargers then there will be the same issue as seen in other countries where there will be a lot of people fighting for their time on the charger.
