I feel they the construction
I feel they the construction of public EV stations is more to ease consumer range anxiety fears than actual functionality. Statistics show that average drivers do not drive enough to need them. Plus, they are still too cumbersome to use for long distance trips - drivers will not recharge for an hour after every two hours of driving or so.
The advantage of deploying EV structure is that everyone has electricity. There are lines everywhere, and this is not the case with gas lines. Singapore, whose government and geography is much better suited to centrally deployed infrastructure, could not tackle encouraging natural gas usage in private cars. It remains to be seen whether they can pull EV deployment. This sort of transition is way more difficult in the US.
