Is there another way to make a player jump out of a seat?

I currently use the jump boolean in the players humanoid however I've just noticed that it is no longer making the player jump which as such is rendering my teleport system useless. Is there another way to make a player jump out of a seat other than this value?

you can make velocity higher when they are not allowed or "not high enough rank"
