Tesla has always been NOTORIOUSLY late actually releasing stuff he promises. (often times the specs quietly get downgraded quite significantly too)
Just look at his power wall as a good example, however Enphase is pretty much kicking his ass there, but anyways.
He may still put the vehicle out.... 10 years from now, when the price of lith finally drops to where he actually can afford it. Or a new tech comes out for storage.
Since he really has not said much, if anything, about any of the other specs of this expected vehicle, except for the price. It could be just about anything, Tesla's version of the Yugo. Maybe he will suddenly decide he likes motorcycles afterall. OH hey look my son likes bikes, so I'll make a bike for him too, like the truck. A bike / bike like vehicle, he could do at that price.
