Molecules of an ideal gas bounce off the sides of the container, not each other.
This reminds me of the other day when my son and I were standing close to several beehives and watching the bees work. I asked him, "How long do you think we have to stand here to get stung?" and he said "a week". A few minutes later one of the bees had gotten stuck in his hair and was working it's way in deeper before stinging him.
Then the gas analogy might be even better: anyone who's been in a room with one or more flies has observed that flies spend a high proportion of their time bouncing off walls and windows.
