While vegeta was shown to be able to punch through hakai but showed no new attacks or techniques in the Top. In the Top goku uses that mine technique and that hexa technique. If you look at their respective fights against broly vegeta used a big bang attack a move he already knows and it's a blast while goku used a new technique which broly copied shortly after it was used and was going to use a new attack on broly. Do you think Vegeta will learn instant transmission With Goku already on Earth and ready to fight Moro, Vegeta is still training on yardrat to master a new technique, once he learns this technique he wont have time to return using the GP spaceship, so the only way the prince can make it in time is with Instant Transmission. To sum things up, it's a safe bet that Vegeta will at least learn a way to put Instant Transmission to much more aggressive use than Goku does - possibly as a way to move fast enough to keep Moro. Goku kept trying to learn, get better control, have a better understanding of, and master ui while vegeta tried it once then gave up on learning it. The technique lets Gas effectively position Vegeta in key spots. While vegeta decided to be the one to train and get stronger. Gas uses Instant Transmission to warp Vegeta to exactly where he wants him to be, just by pointing at the Saiyan with two fingers. He decided to learn the mafuba instead of training to get stronger. He's asked master roshi to teach him more techniques. He's shown an interest in wanting to learn techniques. This quick grasp of the Instant Transmission sees the Yardrats claim he's a prodigy, but it.

Goku should be allowed to keep some things to himself. Focusing for a bit, Vegeta indeed teleports to Earth in time before Goku is completely defeated by Moro.

Trunks knows the mafuba technique and sb. This may seem like a plot hole, but there is a working explanation from a few chapters ago. He learned the principle enough to pull it off once and immediately thereafter said he couldn't do it again even if he tried. But I agree that it would probably just transport all 3 to whoever locks onto a ki signature and moves first.

Only seconds after realizing he would have to teleport himself, Vegeta was able to pull off a long-range journey between planets. Vegeta can do Instant Transmission, since training on Yadrat (Dragonball Super Moro Arc). Krillin even improved it and he's the only person who knows of that technique who did. Some might argue that Vegeta learning Instant Transmission almost instantly is unrealistic. Krillin, master roshi, yamcha, goten and gohan know the kamehameha.
