I've been re-watching Dragon Ball Z and I'm in the Cell arc.
So Tenshinhan and Piccolo are chasing after Cell (first adult form) and if they go fast enough to catch him he can sense their presence then hide himself, but if they go slow enough to mask their Ki so he cannot detect hem they cannot catch up to him. Why didn't they just hop into a fast aircraft and mask their Ki while flying the aircraft in pursuit of Cell? Also, Trunks goes back in time to make sure Goku doesn't die, but if Trunks wanted to destroy the Artificial Humans why wasn't his primary goal to discover the laboratory of Doctor Gero and find the blueprints for the Artificial Humans? Another thing that was puzzling, is that if they're looking for Cell or the other Artificial Humans and they have trouble finding them, couldn't they just use Uranai Baba?
In the previous Frieza arc, there were many opportunities to throw at least one Namekian Dragon Ball into the water to hide it from enemies, yet these tards never did it. Also in the Frieza arc Vegeta was more cunning and would often admit when he was outclassed then plan accordingly, yet in the Cell arc Vegeta goes full retard making countless poor judgements and decisions because "muh pride"?
Something at the beginnings of the voyage to Namek really triggered me. Mister Popo, along with Bulma, use a fucking magic carpet to instantly teleport to the region where Kami's Namekian space ship is located. If Mister Popo had a teleporting magic carpet then why didn't he teleport Goku to fight the Sayajins the moment Goku arrived at Kami's place? Instead people fucking die while Goku is making his way there on Kinto-Un. And why does Porunga bring people back from the dead to Earth instead of removing their halo while they're at Kaio's planet and making them run their ass all the way back across Serpent Road like Shen Long does? Better yet, why wasn't Kuririn, after he was killed by Frieza, re-assembled like Chaozu and able to go to Kaio's planet like everyone else?
