I lost the ATV early in the game, not expecting that hole. And I walked for a long time. It didn't spoil my gameplay too much. But I saved up a lot of fuel, and by the time I was able to get the ATV, I had upgraded its battery and there was no need for fuel, which allows you to use it for other needs.
The hook can be split into two parts on the workbench. This way you get two ropes with one hook at the end, which you won't accidentally lose by hooking both ends on the wall.
At the very beginning of the game, in the very first letter from Dr. Lea (or was it from Bao? It doesn't matter, in the first two letters), there are mentions that you need to periodically do calibration. The fact that you didn't do it means that you weren't even interested in the console commands described in the console itself on the right.
