Guy's Behavior

Guys, What does it mean when a guy offers to drive you home?

There was a American football game involving our small town club and another. It's a public club so anyone can join. We have a guys flag and tackle team and a girls flag team. I'm on the girls flag team and he's on both the guys teams. Anyway that's some background. And after the tackle game we stayed at the stadium to hang out and drink. And I came by bike and live a couple of miles away and I regularly come to pracitces by bike so it was no problem going home. And he bought me a beer earlier out of the blue meaning I didn't provoke him. He did it on his own. My friend left earlier so I was alone with them. There were five guys including him and me. We were having fun and joking around. During that time he filrted with me. At least that's what my friends deduced. And he stood very close to me. So when the time came to go home I jokingly metioned my way of transport and out of the blue he said "I'll drive you" and he did. Don't get me wrong I had a beer or two so I was perfectly capable of using my bike. And I don't live anywhere that's on his route. He has to go around. Anyway I wanna know, would you say that he likes me/ has feelings for me or he just did a good deed because he felt nice?
