Yup, that will be one less reason to live in a city. I've also theorized that work from home and self-driving vehicles are other trends that may counteract the trend towards urban living. If you have a self-driving vehicle (on the highway at least), longer commutes may be less of an issue if you can work, read, or watch tv (we're not there yet.) If you work from home, commute doesn't matter at all.
That being said, I work from home, but I live in downtown to have easy access to activities, restaurants, and supermarkets without needing a car. The difference in rent is dwarfed by not having the cost or hassle of a vehicle.
