Robocar news: Comma One goes open source, creating simulations for robocars in New Zealand earthquakes

There have been few postings this month, as I took the time to enjoy a holiday in New Zealand around speaking at the SingularityU New Zealand summit in Christchurch. The night before the summit, we enjoyed a 7.8 earthquake not so far from Christchurch, whose downtown was 2/3 demolished after quakes in 2010 and 2011. On the 11th floor of the hotel it was a disturbing nailbiter of swaying back and forth for over 2 minutes — but of course, swaying is what the building is supposed to do, that means it’s working. The shocks were rolling, not violent, and in fact, we got more violent jolts from aftershocks a week later when we went to Picton.

While driving around that region, we encountered this classic earthquake scene on the road:

quakeroad

There were many like this and in fact the main highway of the South Island was destroyed long-term not too far away, cutting off several towns. A scene like this makes you wonder just what a robocar would do in these situations. I already answered this question in a blog post on how to handle a tsunami. Fortunately, there was only a mild tsunami for this quake. A tsunami will result in a warning in the rich world and the car will know the elevation map of the roads and know how to get to high ground. In some places, like Japan, there is also an advanced earthquake warning system that tells you quakes are coming well before they hit since electrons go much faster than seismic waves. With such a system, robocars should receive a warning and come to a stop unless they need to evacuate a tsunami zone. Without such a warning, we still could imagine the road cracking and collapsing in front of you as might have happened on this road. Of course, the cones and signs that warned me days later would not be present.

The answer again lies in the fact that pictures (like mine) will be used to create situations like this in a simulator and car developers will be able to test their systems with simulated quake damage. I’ve spoken since 2010 on the value of a shared simulator environment and I think if government agencies like NHTSA want to really help development, providing funding and tools for such an environment would be a good step. NHTSA’s proposal that all developers share their logs of all incidents would clearly make such a simulator better, but there is pushback because of the proprietary value of those logs. When it comes to strange situations like earthquakes, I doubt there would be much pushback on having an open and shared simulator environment.

New Zealand’s government is taking a very welcoming approach to robocars. They are not regulating for a while and have invited developers to come and test. They have even said it’s OK to test unmanned vehicles under some fairly simple rules. NZ does not have any auto industry and it’s quite remote, but we’ll see if they can attract developers to come test. Their roads feature something you don’t see much in the USA — tons and tons of one-lane bridges and other one-lane stretches of highway. Turns out that robocars, with a little bit of communication, can make efficient use of one-lane two-way roads, so it might be worth exploring.

[Editor’s note: Christchurch will host New Zealand’s first trial of a fully autonomous electric vehicle next year. The trials will largely be conducted on the Christchurch Airport campus, starting on private roads with no public present, with the long-term aim of moving to public roads once the safety case has been made and all regulatory approvals are in place.]

Open Source Comma One box

Speaking of Open, today Comma.ai, which previously had declared they were giving up on their neural network autopilot due to NHTSA threats today announced they have open sourced their software, along with hardware designs and case designs. NHTSA did not want them making an autopilot and said they could not simply rely on the fact that drivers were told they must be diligent, It will be very interesting to see how NHTSA reacts to the release of open designs that anybody can then install on their car.

The automotive industry has had a long history of valuing the tinkerer. All the big car companies had their beginnings with small tinkerers and inventors. Some even died in the very machines they were inventing. These beginnings have allowed people to do all sorts of playing around in their garages with new car ideas, without government oversight, in spite of the risk to themselves and even others on the road. If a mechanic wants to charge you for working on your car they must be licenced, but you are free to work on it yourself with no licence, and even build experimental cars. You just can’t sell them. And even those rights have been eroded.

Clearly far fewer people will have the inclination to build an autopilot using the comma.ai tools by themselves. But it won’t be that hard to do, and they can make it easier with time, too. One could even imagine a car which already had the necessary hardware so that you only needed to download software to make it happen.

In recent times, there has been a strong effort to prevent people with tinkering with their cars, even in software. One common area of controversy has been around engine tuning. Engine tuning is regulated by the EPA to keep emissions low. Car vendors have to show they have done this — and they can’t program their car to give good emissions only on the test while getting better performance off the test as VW did. But owners have been known to want to make such modifications. Now we will see modifications that affect not just emissions but safety. Car companies don’t want to be responsible if you modify the code in your car and there is an accident involving both their code and yours. As such, they will try to secure their car systems so you can’t change them, and the government may help them or even insist on it. When you add computer security risks to the mix — who can certify the modified car can’t be taken over and used as a weapon? — it will get even more fun.

I will also point out that I suspect that comma’s approach would not know what to do about the collapsed road because it would never have been trained in that situation. It might, however, simply sound an alert and kick out, not being able to find the lane anymore.

Regulatory pushback

Regular readers will have seen my strong critique of the NHTSA rules. The other major news during my break was the pushback from major players in the public comment on the regulations. In some ways, the regulations didn’t do enough to give vendors the certainty they need to make their plans. At the same time they were criticized for not giving enough flexibility to vendors. In addition, as expected, they resist giving up their proprietary data in the proposed forced sharing. I predict continued ambivalence on the regulations. Big players actually like having lots of regulations, because big players know how to deal with that and small players don’t.
