This gives you more of an idea of the dome’s size. Toyota says the purpose of the machine is to see how people respond in driving when they are tired, sleepy, etc.
But it’d be a good machine to simply test people’s driving skills and see if they’re fit to drive.
Toyota says that’s not the purpose of the machine.

This is the view from inside Toyota’s new driving simulator: The Lexus is real, but the landscape is all computer graphics.
The simulator is a giant ball that tilts and cocks, and swooshes on a rail in a huge warehouse-like building (See the other photo above to get an idea of its size).
NHTSA has a similar machine.
Toyota refuses to say how much it spent on the simulator.
