Being Used?

Ever since college started, I've made this new friend in my English class. He's white, and fairly obese. He's the one who sucked me into playing Legend of the Five Rings, which I have to admit to being addicting and fun. A while back I drove him out to the card store up in Dublin (about half hour from Fremont), which is the only local card store with an abundance of L5R players. Ever since then, he's been calling me and asking me for rides to places. Apparently his bicycle broke so he has no reliable transportation besides bus. He lives about 5 minutes from school, but can come up to 10 minutes with traffic. It's in the opposite direction of my house too, so that makes for an even longer trip home. He asked for a ride home one time, which was okay. Another time he asked that I come pick him up from home and drive him to school when I was ALREADY at school. I found that to be a little ridiculous. Just the other day, he asked that I come pick him up from home again and take him to school, but I evaded it with a fabricated excuse. So instead he asked if I could take him to school the following day. His quick succession of request made it obvious that he's trying to find every opportunity he can get to mooch a free ride from a fellow "friend". I've been actually giving him a lot of excuses lately, and I can't go about doing that forever, so I agreed to picking his ass up the following morning.

What sucked was that he lives out in the ghetto parts of Hayward, so the traffic in the morning is terrible. The *coughmexicancough* drivers out there are ruthless! They'll cut in front of you at any given opportunity. I like to call the drive to school, a "war zone" because it always feels like I'm battling, or racing against traffic. I don't mean racing like a race track, but more like fighting for emptier lanes and squeezing through yellow lights when behind a slow-ass car. You have to constantly assess the traffic in order to determine which will turn out being faster in the long run. Just because a lane is emptier doesn't mean it's faster. You have to factor in big slow trucks and people who could potentially be turning into parking lots and whatnot. If you choose the wrong lane or fail to switch to a better lane in time, you could easily be trapped in a slow or frozen lane. As soon as I see 5+ cars pass me in the adjacent lane, I know I screwed up.

Anyways, I picked up my friend and we were driving to school, but then he said "Oh shoot! I forgot my english essay at home!" Since I'm in the same english class with him, I knew what he was talking about... Unfortunately I ended up having to turn around and drive his ass back to his house just to pick up his essay and then drive him to school. I ended up arriving to school half and hour later than usual having a last second speech to prepare and math test to study for.....

Now if this guy were a close friend, I'd be totally fine pick him up, but that fact that he's using me so much is becoming a problem. I mean look:
He's 23. That's 5 years he's been at a community college and is still looking to transfer out at some point.
He lives in the basement of a random mexican family's house because he couldn't afford rent at a real place. I think places like this can be found on craigslist.
He fails to arrive to school due to sleeping in. Worst excuse ever.
He skips classes!
He has missed more math classes than I can count. He doesn't even know if he's been dropped or not.
He forgets to write his english essays. He almost got dropped from english. If I didn't take him back home to get his essay, he might've really been dropped!
He skipped class hoping to play cards with me but I refused.
He's unemployed.
He unfortunately smells very bad and his hair always looks very oily. Even though I'm judging him so much, I think that hygiene is an absolute necessity in one's social life.

If he was a better influence as my senior in college, I would maybe look up to him more, but with that kind of background, it's obvious he's only using me. I'm too kind (yet judgmental on the inside). I really need to do something about this guy. I don't like to be used.

While working on cars with my dad today he said my grandpa's belief was that "friends are only friends if they can get something out of you". I'm still skeptical, but it seems plausible.
