The car has to have electric power steering that takes forged external commands. ~2005 cars tend to have incompatible hydraulic type units, 2019~ cars tend to have signature enforcement for external steering input.

Gas, brake, steering in cars are controlled by each separate computers with each own firmware - there's no centralized keyboard controller or USB root hub to take over. The computers have to be designed and built to accept driving commands, or replaced by one supporting it, or mechanically actuated. The latter two paths are rarely taken.
