Shift Cars

The Shift Cars (シフトカー) are miniature cars created for the purpose of helping humanity. They are used by Kamen Rider Drive in conjunction with his belt, the Drive Driver, and bracelet, the Shift Brace, which work together via infrared. Some Shift Cars enhance Drive's current Type form with a Tire Exchange, adding the last part of a Shift Car's name to his current Type (i.e, Type Speed Flare). Some Tires come with a weapon for Drive to wield.

They are able to attack Roidmudes by traveling on special tracks that they spawn, and are strong enough to incapacitate unevolved Roidmudes. As long as someone has a Shift Car on their person, they are able to ignore the time distortions a Roidmude emits when active, unless multiple time distortion effects occur. In this case, one must have multiple Shift Cars on their person.

Their most unique attribute though is their capacity for sentience and sapience. Though they cannot speak, Shift Cars can feel emotions such as mischievousness, frustration, happiness and even more complicated feelings such as regret and loss, and can show these emotions through their beeping or through car signs they spawn alongside their tracks.

They can be controlled by Mr. Belt, summoned by Shinnosuke and Kiriko by calling their names, or can simply come of their own volition. Throughout the series they are off investigating their own cases, but return to Drive when they are done gathering data to assist him in battling Roidmudes.

Devices similar to Shift Cars, known as Viral Cores (バイラルコア), are used to evolve lesser Roidmudes into more powerful forms. Chrome versions of the Viral Cores are also used by Drive's rival, Mashin Chaser.
