Electric car: No one ever did it successfully, except Tesla now profitable with that.
Storage battery: Tesla jumped on this bandwagon when it became profitable more than anyone else, and is now going to be a leader in that area.
Solar collection: Obviously a part of the Tesla story.
Automation of cars: Tesla jumped on that bandwagon, and expect similar results to the first two.
Trucks: Tesla is not the first to electric trucks, but when they do it, expect similar results to the first two.
For instance: automated trucks. Think if you are a county government who maintains roads (100% of counties in USA). Over half your wear and tear, road maintenance cost, road cost, goes to your chosen garbage monopoly. Their trucks rumble through at full tonnage stop and go. Hugely polluting, hugely damaging. 40 tons. Dirty fuels. Tesla Truck: can have a smaller car-weight unit at only 2 tons on each block, filling up its carrying capacity, then drive back to the main truck on the truck route to deliver the garbage. Not only is this less expensive total cost of ownership to have electric non-polluting non-manned garbage trucks, but it also saves on half the cost of road maintenance. Whomever gets into the automated electric garbage truck business stands to gain a huge amount. We'll see if they do this or just get some of the business as a platform provider and a value-added company does the rest.
