The bus is an NPC-driven vehicle that travels in a clockwise direction around the highway, stopping at the Peräjärvibus stop once every circuit. It spawns at a semi-random spot on the highway depending on the in-game time when the game is loaded, along with its passengers. It costs 25 mk to get on the bus. After paying, the player can sit in any of the seats by pressing ⏎ when the passenger mode icon comes on the screen. If the bus gets stuck for a significant period of time, the bus driver will leave the bus frustrated and will only return once the game has been saved.
The bus is the slowest accelerating vehicle in the game, taking about a minute to reach its top speed from a standstill. However, the driver doesn't normally exceed 80 km/h. Due to its slow speeds, the bus will usually be overtaken by other cars seen on the highway.
There are buttons above each seat to stop the bus if the player wants to get out at the next bus stop. The bus can also be boarded from any of the bus stops along the highway, the bus will stop if the player character is standing at a stop.
The bus driver, Kari Lätänen
The driver of the bus, Kari Lätänen, looks to be a middle-aged man wearing glasses and a blue bus driver's uniform. He has short brown hair and a mustache. He also wears jeans similar to that of the drunken brawler.
The bus operates all day, even during the night on a schedule. The bus has text on the front, sides, and back that read "Lätäsen Liikenne Oy" which translates to "Lätänen's Transport Ltd."
While this is the 'official' timetable that it posted in bus stops, the bus may not exactly stick to the schedule, especially if you get on/off the bus at one of the request stops - the bus then needs a long time to accelerate to highway speeds. The bus only makes sure to leave on time at Peräjärvi.
