Should she keep letting her co-worker carpool?

“I work for a small business and my coworker recently had to sell her car due to some personal stuff. Over the last two months we’ve carpooled, which takes me an extra 20 minutes daily. Some mornings I’ve had to wait almost 10 minutes for her to be ready. I want to stop, but I’m feeling extremely guilty because she won’t be able to get to work.”
