CGX car nut:

Despite the wishes of our collective ruling class elite, liquid fuels offer significant tangible benefits include energy density when compared with battery based EVs.  Porsche, and potentially Formula One, are on the correct strategy of pursuing a synthetic liquid fuels for transportation.  If done properly, this will extend the life of current petro and diesel powered vehicles for decades while still providing a reduction in carbon emission profiles.  

Fossil fuels will be around for a very very long time. Not certain if they will be more or less expensive but in my most humble opinion the synthetic fuels Porsche are working on are only going to be suited for a tiny fraction of very expensive sports cars.
