Conventionally, companies that develop launch vehicles have all physical "steering" done in a combination of two methods: 1. Most launch vehicles are not controlled manually, if that is what you are asking.
Bonus: Dragon V2 control panels are modified 17" Tesla Model S touchscreens and include the same Nvidia Tegra SoCs. In about 24 hours, Crew Dragon will be in position to rendezvous and dock with the space station.
SpaceX is developing a super-heavy lift launch system, Starship. The launch escape system manual control is located in the center, easily reachable by both astronauts.
SpaceX engineers perform what they call "Cutting the strings" where they randomly shut off a flight computer mid simulation, to see how it responds. SpaceX is targeting Wednesday, May 27 for Falcon 9’s launch of Crew Dragon’s second demonstration (Demo-2) mission from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. SpaceX's Starship spacecraft and Super Heavy rocket (collectively referred to as Starship) represent a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond. This test flight with NASA astronauts Bob Behnken and Doug Hurley on board the Dragon spacecraft will return human spaceflight to the United States.. The SpaceX reusable launch system development program is a privately funded program to develop a set of new technologies for an orbital launch system that may be reused many times in a manner similar to the reusability of aircraft. SpaceX has been developing the technologies over several years to facilitate full and rapid reusability of space launch vehicles. Starship is a fully reusable second stage and space vehicle intended to replace all of the company's existing launch vehicle hardware by the early 2020s; plus ground infrastructure for rapid launch and relaunch and zero-gravity propellant transfer technology in low Earth orbit (LEO). Dragon uses a similar triple redundant system for its flight computers. Once in orbit, the crew and SpaceX mission control will verify the vehicle is performing as intended by testing the environmental control system, the displays and control system, and the maneuvering thrusters, among other things.
