On this page of the Breathedge game guide, you will learn how to get the first vehicle in the game, which will allow you to move faster on the map.
The first vehicle in Breathedge is the vacuum cleaner. To find it, you need to go to the cave in the asteroid during the second chapter. At the end of the cave, there is a broken ship floating in the air, and next to it there's a vacuum cleaner stuck in a small asteroid.
By riding the vacuum cleaner, you can accelerate to fly even faster. The duration of acceleration depends only on the kind of accelerator you have equipped. Of course, the oxygen level will drop just as it would if you weren't riding the vehicle. You can craft fuel with resin and repair the vehicle using the Repair tool. Later in the game, you will also be able to craft another, faster vehicle: the ZAZ-1. It has a cabin, so you won't lose oxygen while using it.
