Always Late to Pick me up

Hi, so I've actually posted about this friend before about her not being really emotionally supportive and I came to the conclusion that I just wouldn't get that from her and she'd just be a friend for fun times. But...

We both have jobs by each other I started at my job first then she started hers later and at some point she was like, "Oh, I should give you rides!" and I was like "Okay."

So she started giving me rides. We agreed on her getting me at 6:45. The first day she was on time then the next she was late, 6:50 for a few days, then 6:55 for a few, then 7:00, then 7:05, then 7:10, and a few times she even came at 7:12. And this is over a few months.

After work I walk to her building so we can meet up and go to her car. We get off at the same time, so usually she would have to wait a few minutes for me to get to her building since it's like a 5 minute walk. At first I would walk there and she'd be waiting, then it'd be me waiting a few minutes, then 5, then 10, then 15. I have been consistently waiting for her for 15 minutes after work and sometimes she comes out as late as 25 minutes after work. And we both have jobs where when shift I'd over its over. We don't work fast-food or retail or anything like that.

I asked her about it a few times and she's like "Oh I have to say bye to everyone." Another time she said "Oh well I forget it's time to go," or "It's just that I start a task and I try to wrap it up and everything." And honestly I totally get that, stuff happens. My thing is just how are you consistently late. It's not oh I wat 15-30mins every now and then. It's everyday.

I then asked her if she could be more on time. Pick me up at 7 and come out at a reasonable time after work and she said okay.

First day after she comes at 7:05 which is okay cause she's trying. Then when I get to her building she's already outside. Great. Next day she picks me up at 7:03. Great. Then after work I wait like 5 minutes. Okay. For the rest of the week she was consistent at coming within 7:05 and I only had to wait for her for like 5 mins after work.

Then this week. She has me wait till 4:25. When she comes out she doesn't even say my bad or anything. Like it doesn't matter that I was waiting almost 30 mins. This morning she picks me up at 7:12. Again says nothing.

Maybe it's just a one off, but I just don't know.

Am I being unreasonable to try and put her to a schedule when she's the one giving me rides? I never asked and I would never make her feel like she has to but I just feel like if you're gonna offer you should be on time and consistent if you're giving someone else a ride.

Am I wrong?
