Back to the future is such bullshit because it is impossible for Marty to see his own future.
If Marty time traveled from 1980 to 2019, he would find out that he doesnt exist in2019 because, to the rest of the world, he "vanished"
He cant travel to the future and live in the present at the same time. He cant be in two places at once.
That means the future that Marty was an alternate timeline.
Also on Avengers: Cap could travel to the past and live his life there because his "past self" was frozen. Therefore, he cant bump into himself or create inconsistencies with family and friends and cause paradoxes.
Not exactly true.
Depending on which time travel theory you are going by Marty could very easily see his future self however his future self would remember seeing his future self which would affect the interaction
