This is a common fallacy. If there is already somewhere to park the car, then you already have somewhere to install charging. In a highly developed city like Singapore, the electric grid already extends almost everywhere.

Batteries aren't free, but neither are electrolizers and fuel cells (limited life span, large quantities of platinum and rare earth metals needed for catalysts, etc). The lifecycle efficiency of battery electric vehicles is much better than for hydrogen fuel cells, and the infrastructure requirements are much more managable.
- raaaaraaaa2 7y agoThere's serious engineering problem - you need CHEAP material which will be able to handle: 1) very high pressure 2) ultra precise sealing 3) material needs to be resistant againist hydrogen embrittlement (problem for all metal materials) ...in order to build cheap vehicle which will lasts at least 10 years.
- Dumblydorr 7y agoBatteries will get greener over time. Their main components, lithium, steel,aluminum, carbon, water, these are not dirty materials. Cobalt and other rare metals, yes those must be minimized, which may be why Tesla bought Maxwell which has non cobalt cathode tech, and which has supercapacitor tech that may supplement the battery. In short, EVs will get cleaner over time, let's not throw them out or slow adoption. We desperately need a cleaner atmosphere and they will somewhat help with that by replacing ICEs.
