Hey! Who put that barrier there! 
2:10 race 1: this is a good example of vision probably being a bit too focused on what’s directly ahead, which is normal considering it’s first race. That’s a lot of karts and visually quite intimidating.
Look through the guy ahead, not at them. Try to make sure you are taking in the big picture. Move your sight around and greedily take in as much detail about the big picture as you can.
The mind stores the info you give it. The kart directly in front of you does have to be glanced at repeatedly to place it in space/time but in general your mind will deal with it peripherally, vision wise. Trust that you will see it without looking at it directly, look through and ahead.
Anyways, that’s how you avoid wrecks ahead, by seeing them evolve, which you can’t do if you are focused on the here and now as opposed to also having an awareness of the track two or three seconds down the road.
If you mess around in practice:
Try a bit where you deliberately focus far down the track and see how it goes. You should notice that being too far forwards leads you to be early on turns and missing apexes, cutting them off. The feeling you get when visual is far ahead and doesn’t have any “here and now” info is called being “ahead of the kart”.
If you do the opposite and force yourself to only focus on the 10 foot sphere around you, not taking in any “ahead” you will find yourself hitting apexes well but holding the turn too long, struggling to exit well. This is called being “behind” the kart.
Where you want to be is “on top” of the kart and you achieve that by mixing it up visually. Take it all in, eyes active, moving. Never dwell.
A way to train this is to think of the turn as a series of things you look at:
Big picture approach, then sight the brake point. Shift vision quickly to sighting apex, back to brake point and brake, shifting vision as you hit brake to quickly check apex, but then look ahead and though to track out point as you turn in. Ignore apex as you know where it is already, maybe look down at apex to say hi as you go over it and then immediately look down back to track out area, etc. Mid turn you are looking down track to next turn. The apex you are in is history at that point. It’s your present moment but effectively all the decision making to get to this moment occurred in the past,
Basically figure out a sequence of visual markers but have them such that you are focusing more on what’s ahead with brief moments of recording the near term stuff.
How you see the race is a deliberate and trained thing. Our default vision is the 10 foot bubble of proximity. That’s where all the imminent threats and opportunities are. But, it’s too narrow focused. Ya gotta feed it near and far and that takes deliberate effort and practice.
I don’t do a good job of explaining it but you get the concept. Play with the idea and make your own version of it.
