Will the Google Car drive at 200 mph ?

No, but it will take you door to door, departing instantly when you're ready and not before, and it won't stop in between unless you want it to.

The congested road network still happens with Google cars.

[giardini]

Does it, even when cars movements are coordinated and all driving automated? How congested?

Regardless I would want to see a cost-justification of high speed rail vs auto vs standard train vs buses, etc.
