I wonder if this could put a real dent in rush hour?

(Letting my imagination wander a bit)

If everyone on the highway did this...

Could Uber be more convenient than public tranit?

Would they be able to regularly group passengers so that people are picked up and dropped off nearby?

Could Uber be cheaper than parking garages in large cities?

Could this put such a large dent in the number of cars on the road that traffic moves faster?
