Global Freeze

Global Freeze (グローバルフリーズ) is an incident in which the Roidmudes somehow caused time to stop. Evidently, this incident occurred all over the world, with devastating Roidmude attacks occuring at least across Japan and it's neighbours in East Asia (North & South Korea, China, and Russia). During this event, various cities were heavily damaged and an untold amount of civilians were injured and/or killed. This event was eventually stopped by an unknown individual who had Drive's powers and the Shift Cars, but not before Shinnosuke Tomari accidentally injured his partner in a terrible accident while on the job.

Aftermath
Six months later, the Special Investigation Unit has called this phenomenon the Heavy Acceleration (重加速), while the public has dubbed it the Heaviness (どんより). In order to prevent the Global Freeze from happening again, the Tokyo PD urged citizens via billboard PSAs and special phone apps to contact emergency services if they see any signs of the Heavy Acceleration effect in progress.
