Why does EVERY single plat immediately run for the left or right boost on kickoff instead of waiting literally 2 seconds for defense?

This has always seemed like the most braindead thing to do, as unlucky kickoffs can happen at any level. I cannot count the amount of opponent kickoff goals that i’ve prevented just by holding goal for 2 seconds during kickoff because someone fucks up a speed flip (as I also do sometimes) or you just get unlucky.

Immediately lost a 2v2 game in OT just a few minutes ago for this exact reason 😐 bricked my speed flip because accidents happen, and tm8 was nowhere to be seen as he was in the corner getting boost lol.

Is this simply a circumstance of lower level games or does this happen at higher levels as well?
