<human>: Can you give me a shortened version of the text?

My roommates brother just moved in to our house, and he works at the same place I do. He had a piece of shit Mazda rx8 which was a lemon to start out, and eventually was essentially given away due to mechanical issues. Now he has a motorcycle that continuously is not working, and he has been talking about selling it so he can get a car. He works in the USAF but for only about $8 an hour and at the airport with me. I have told him id help him look for a car,and sell the bike but I get nowhere with it and it stresses me out so I stopped. Not my problem. 

I love the guy, he's a good friend but today he texted me and asked for my schedule so he can ride with me. The text read "hey what's your schedule so I can ride to work with you". I'm not a greyhound or a taxi. I don't want to have to wait for you to get ready, wait for you after work, feel like i'm always being rushed etc. I don't like feeling like this, I don't like feeling like an asshole but I feel I'm being taken advantage of and I'm not going to tolerate it. He smokes a lot of weed and I think being high all the time has something to do with the lack of motivation to get his own vehicle. 

What should I do or say?
<bot>: lazy roommate insisting for ride to work, has a motorcycle but is too lazy to sell and buy his own car. Wants me to be his taxi since we work at the same place.
