How about:
Tesla start building 3 more GFs, China Europe and USA. No joint venture needed in China. India allow Tesla to sell cars without factory.
SA TE project built on time. Puerto Rico next, complete 100% tesla rebuild of entire island. And TE profit increase 10x.
And tesla announce they swap chemistry to Toshiba niob in GF over night, easy transition
chargetime only 6minutes to 80%, and all superchargers is upgraded to support this charge rate.
Tesla semi is sold out through 2020. Sweep all competition away.
Only New is quick chemistry change which might be far fetched. Other points i think will happy within a year or so.
