That idea is very cool; but I feel it introduces a whole new amount of complexity.
Making a car that drives you (safely) somewhere is the problem Google is working on.
Delivery of packages along a route is a whole other matter; for example I live on a street with a weird t/fork at the end. Vans tend to struggle getting in and out.
The decision making process to effectively get a van to my door probably still one that requires human input :)
The autonomous cars had to solve problems much more difficult than this in the DARPA challenges. Stanley and Junior have been thrust into artificially complicated mazes and come through with no problem.
