A virtual reality system, combined with surrounding visual, auditory content and motion platform, can provide an immersive experience including a sensation of motion. However, the space and cost requirements for installation of motion platforms hinder its practical use. To overcome this issue, we have proposed to use a car as a motion platform. We tested an immersive content in which users ride on a trolley in a virtual space, on two types of automatic driving algorithms. The results showed that this system enhanced "enjoyment", "sense of fear" and "feeling of movement" of the content. Comparison of algorithms showed that "acceleration feedback" is more advantageous than "jerk feedback".
