Reserves is a kind of dodgy term. Never trust a table stating what the reserves are, unless it's something well-studied like oil (which will have dozens of different charts, depending on what you mean by "reserves"). Like oil, lithium will keep being produced as long as the price keeps rising, as new reserves are found or uneconomic reserves become economic.
It's more a question of price, how quickly it rises, and what the alternatives are.
Unless the reserves turn out to be at least 20x larger than that table, all electric lithium-ion is not going to happen. Are you saying that that table is off by 2000%?
Sure, it's not a fixed reserve but a smooth price curve. That doesn't mean a lot in practice; people aren't going to pay millions to extract every last bit of lithium from the earth. The point is that lithium-ion batteries for cars are most likely not going to be the long term solution. The same applies to solar panels and fuel cells that have rare materials in them by the way.
Just to note that lithium is not like oil: the lithium is not consumed in making the batteries, so if it turns out to be useful it'll be worth gathering even from low quality sources.
Also, sea water is 1-2ppm lithium -- expensive but plenty of it to extract.
I could imagine driverless cars reducing the total number of vehicles we need to own as a species by an order of magnitude, perhaps more. That might help.
