Smart cars in driverless convoy breakthrough

Volvo says it has successfully tested a “road train” of vehicles driving automatically behind a lead vehicle on the public roads of Spain.
Smart car systems have the potential to improve safety and fuel efficiency by using communications between vehicles to optimise speeds and avoid collisions.

In-car technology: the road aheadCar makers around the world are working on such systems and Volvo claims its Sartre system has scored a world first by being deployed among other road users outside Madrid.
"Driving among other road users is a great milestone in our project," said Linda Wahlström, project manager for the Sartre project. “The vehicles drove at 85km an hour. The gap between each vehicle was just 6m.”
According to Volvo, the system builds on radar, laser and camera safety features already including in smart cars, with a wireless network connecting the convoy cars to the lead vehicle.
“The vehicles in the platoon 'mimic' the lead vehicle using Ricardo autonomous control - accelerating, braking and turning in exactly the same way as the leader,” the company said.
Green light
Although the concept retains elements of science fiction, Volvo said the technology could be deployed relatively easily because it didn't rely on changes to road monitoring systems or basic car manufacturing.
"We've focused really hard on changing as little as possible in existing systems,” said Wahlström.
”Everything should function without any infrastructure changes to the roads or expensive additional components in the cars. Apart from the software developed as part of the project, it is really only the wireless network installed between the cars that set them apart from other cars available in showrooms today."
The researchers claim the technology could lead to a 20% reduction in fuel costs in motorway conditions and improve road capacity, while drivers would be able to work on a laptop while on the road.
Ready market
Okay, so their first market is surely to parents who can travel in the first car, with the noisy kids in the following car.
What? 8-)

Which Idiot....
put computers in cars in the first place?
And now makes them drive automatically?!!!

The defendant looked at the judge and said...Sorry your honour , it's wasn't my fault I was speeding.It was the car in front who's responsible. :-)

No thanks.....
What would happen if some kind of interference interrupted the Wireless network? The 'driver' wouldn't exactly be paying attention as the car is driving itself?
"m'lud, the computer crashed....followed shortly by the car"

A fantastic idea in principal, but...
...I can't help thinking of all the many potential drawbacks and hazards.
As above, what happens if there is interference in the network - accidental of malicious? Would terrorists / rogue 3rd parties be able to launch a malicious virus into the system? Imagine mass high-speed collisions up and down every single motorway in the country during the morning rush hour.
What if it were more simple than that, and the guy in front (terrorist / deranged loon / manic depressive) just decides to drive off the edge of a cliff, or straight into oncoming traffic?
I LOVE the idea of driverless cars, I really think they're the future, but it'll take a lot more than a few 'ideal scenario' tests to get me to take my eyes off the road.

So what's new?
I thought Volvo's had been going around without drivers for years.....

Its gonna happen, like it or not.
Whilst its easy to spot all the potential drawbacks, the "upside" is too good for the powers that be to ignore.
The most important is that such a system would considerably reduce congestion, by enabling 'intelligent management' of traffic to eliminate (for example) those delays caused by arbitrary braking and consequent 'wave' effects.
It won't happen next week, but happen it will....

Legalities
Since I doubt that there is any legal provision for issuing a driving licence to a computer, there must surely be a licensed and insured driver sitting in each vehicle, and that driver must be legally responsible for any accidents that occur.
Also the modifications to the vehicles would have to be accepted by an insurer. I am surprised that it was possible to do this. Suppose you hitched up your laptop to your car's engine management system and steering. Imagine the response when you call up your insurer to let them know.
I would very much like to know how it was all legally arranged, and why it was approved. Who do I (or my insurer) sue if such a vehicle hits me?
