With this many order would takes about 3 seconds to get new investors to build another 5 factory to produce these many cars... I don't get it why some people whining about this, this cannot be done.
By the way I just saw that in Saud Arabia the "boss" just made a 2 Billion dollar investment found, when no more oil will be available around the Earth to do some proper business ideas. So this is the time to get together and create more factories I guess.
