Krim Steinbert (クリム・スタインベルト) was a scientist who invented and is conscious within the Drive Driver (ドライブドライバー), affectionately nicknamed "Mr. Belt" (ベルトさん) by his user, Shinnosuke Tomari. He acts as a monitor for the Shift Brace when Shift Cars are used in his transformation bracelet. Aside from being able to control the Tridoron remotely, he can also use the Shift Speed Car as his own body.

History
As the inventor of the Drive Driver, Krim Steinbert was attacked by Heart in his mansion. It is still unclear how he had managed to install his conscious into the Driver, but Mr. Belt would often remember Steinbert's death through his dreams.

Personality
"Mr. Belt" is a straight laced piece of technology, and is honest about his words.

Portrayal
Krim Steinbert, who is also the conscious of the Drive Driver is portrayed by Chris Peppler.

Conception
The Drive Driver has been noted by producer Takahito Oomori as Drive's version of K.I.T.T., the automobile housing an artificial intelligence in the TV series Knight Rider, keeping with Drive's description as 'Kamen Rider meets Knight Rider'.
