Heavy Acceleration

The Roidmudes are capable of slowing down time itself to a crawl known as the Heavy Acceleration (重加速), often referred to by the public as Heaviness (どんより), which slows down everything in it except for Roidmudes and Kamen Rider Drive & his equipment.

As long as someone has a Shift Cars on their person, they are able to ignore the time distortions a Roidmude emits when active, unless multiple time distortion effects occur.
