This is a totally impractical proposal that ignores the fundamental congestion problem.
A seated person takes up 4 sq ft of space. A car takes up 120 sq ft. This makes its spatial efficiency 3.3%. The pods might bring this up to 7%. That's not much of an incremental improvement. By contrast most public transit vehicles allot 8 sq ft per person or less with standing. That's a spatial efficiency of at least 50%.
The point is that any proposal that is based on personal transportation will be subject to the same congestion problems that today exist for cars. They are non-starters. There simply is not enough space for everyone to travel in his own personal limousine, regardless of how it's powered or controlled.
