<human>: My friend and I make a similar income (her slightly less, but she probably thinks I make considerably more). She and I are both very frugal and we often share food when we go out that we split 50/50. However, I feel like the financial burden of the friendship ends up falling a lot more on me because I am the only one with a car. For occasional trips, I would never think to ask a friend for gas money or expect them to offer. However, often when we hang out, I am expected to pick this friend up and drop her off at her house. I have also used my car to help her move and she has also asked for rides to other places such as to see her boyfriend on the rare occasion and this was out of my way. Not only that, but I also cook for her far more often and provide the lion's share of emotional support in this friendship. 

I think she was raised to believe that friends don't ask friends to pay for gas once you have a job and I am the same. However, she has no intentions of getting a car anytime soon. We also have lots of mutual friends and she expects me to pick her up and drive her home after any events or get togethers without even asking and she is about 20 minutes out f my way round trip each time. I can afford to cover the gas too, but I just wish she would offer because I feel taken advantage of. I would probably not even accept the money because that is rude too, right? So what do I do?

Can you give me a shortened version of the text?
<bot>: Friend expects me to drive her places all the time and never offers to pay for gas-but I don't know what to do because it seems petty!
