This is a pretty abysmal take, in my opinion. When public transit is done well (and to be clear, I'm not saying it's done well in Austin), people will use it instead of driving. For example, I used to drive almost everywhere when I lived in the Houston area. After I moved to the Bay Area, I walk, bike, or use public transportation for 95% of my trips, and only use my car when going to the beach/mountains/camping/etc. with friends.
If you are someone who loves driving, it is in your best interests to have well-designed public transit. It means there will be fewer cars on the road and you'll be stuck in less traffic, which saves you time. And, it means people like me can save money and be healthier by walking, biking, and taking public transit instead of driving. In fact, for trips that are <2 miles, biking is usually faster than driving for me here, making it kinetically favorable.
Right now, we are stuck in the high energy transition state between two energy minima, which is what results in these non-idealities. But if Austin commits to doing this right (and in a cost-effective way) I think it'll be very good for the city in the long run.
