Wow, you opened a can of worms because everyone has their own opinion on this. In general, I personally don't recommend it:
1) without asking
2) without a bit of knowledge about drafting
3) making sure the person knows that you're new and may not be able to take a pull
The person in the back is the one at risk. If you touch his back wheel YOU are the one who will go down at 20 mph. If he doesn't know you are there, he may brake, slow down, stand up, etc. In a real pace line, the lead won't do these things (or shouldn't). Also, it is generally proper etiquette to take your turn. Now, if you can't hold that pace you don't have to hold the lead for very long. But, you also need to know how to cycle through a pace line. This topic can go on and on and on with everybody pitching in their 2 cents.
Me? I generally don't like someone jumping in behind without asking except at organized century rides. I ride out in the country here and if a strange man suddenly was right on my rear wheel without saying anything (especially as noisy as the wind is), I'd assume he is either a rude jackass or dangerous. It just makes me very uncomfortable. At organized rides, someone can jump in behind me but they better be willing to take their turn and quickly show that they know how to draft safely.
I don't think that what you did was bad; I'd just ask next time if you could "sit in" a bit and learn, and next time, you'll be pulling. Kind of fun to be whizzing along like that, huh?
