Nope.
You're confusing some sort of sci-fi 'car train' computer controlled mass transport system with individual cars operating within a road system that has both driverless and driven cars.
The example you've given of the car stopping suddenly because a kid ran in the road, the current systems would brake the car if the driver failed to react. If cars behind were fitted with the same technology then they'd react to the car that had braked, in the same way as humans do!
None of the scenarios you've outlined there, are beyond the current technology
Lane change technology - tick
Radar controlled sensors - tick
Nav - tick
Road condition sensors - tick
Controlled and emergency braking systems - tick
These driverless cars DO exist and are currently in the testing phase.
And my point about the guy with the classic car?
I don't deny any individual item but they don't add up to a system cos a system is by definition more than the sum of the parts.
