I highly disagree. Instant decisions usually suck. Forgot to order pepperoni? I'll get that next time. Took out $20 but should have grabbed $40? Slide your card back in. Voted for the wrong candidate? You screwed up on an important decision.
You should take time to decide on what your vote affects. How will your candidate affect you, your family, your neighbors, your country? Are you voting for someone because you think they can do a good job or because you want the clown circus to continue? That's all important to consider so maybe a little line time will do you good.
Secondly, if there is a line then people are OUT VOTING. How is that a bad thing?
Finally, get up earlier and vote first thing you lazy bastard! There are never lines at 6:00am.
