As with most other vehicles on the highway, the Hayosiko used to spawn when the player entered the highway for the first time during a game session. However, it was removed in the 12 August 2021 update and replaced with the Hayosiko Lamore.
Trivia[]
The name "Hayosiko" is a reference to a Finnish joke about fictional Japanese names, where there's a car mechanic named "Hajosiko Toyotasi" which translates to "did your Toyota break down?"
This vehicle was briefly shown in the official trailer, despite being a deleted vehicle. This is because that part of the footage was shot a long time ago, and a closer look suggests that it is a considerably older version, as all the highway vehicles do not have license plates.
The Hayosiko was one of the 3 vehicles that both the player and AI were able to drive, the other vehicles being the Gifu and Roaming Boat
In an experimental update it received a license plate, SWK-776.
