The National Basketball Association has in collaboration with the video game publisher Take-Two Interactive created an e-sports league in the US.
The number of human interventions in journeys made by driverless cars from Google company Waymo in California more than halved in 2016.
There were only 124 "disengagement" incidents last year, where a driver had to take control of a test vehicle on public roads, down from 341 in 2015.
The cars drove nearly 636,000 miles last year, compared with just over 424,000 in 2015.
Other states in the US do not require such reporting.
The California Department of Motor Vehicles published the annual reports on Wednesday.
"Disengagements are a natural part of the testing process that allow our engineers to expand the software' s capabilities and identify areas of improvement," Waymo said in its report.
The most common reasons for interventions in Waymo cars were "software discrepancies, unwanted manoeuvres of the vehicle and perception discrepancies", according to the company.
Of the 124 incidents, only 10 were caused by the "reckless" behaviour of another road user.
Beyond Waymo's impressive results, the news was generally good.
Cruise, the start-up leading General Motors' autonomous driving development, upped its testing in San Francisco markedly. It went from driving fewer than five miles in June 2015, to nearly 400 in June 2016.
It reported 414 disengagements in almost 10,000 miles of driving in 2016 overall.
For some companies the records show a very small amount of mileage covered by the autonomous cars.

In other US states with self-driving regulations - including Nevada, Michigan, and Florida - there is no requirement for public disclosure of this type of data, which is why, for example, not much is known about Uber's autonomous vehicle testing.
Ford only reported 590 miles driven in 2016, all in the month of March. It only has two autonomous cars in California, but has a much larger fleet in Michigan, where reporting is not required.
Meanwhile BMW recorded one disengagement in its 638 miles of autonomous driving in March and April 2016, because lane markings on Highway 101 were not clear enough. The operator's reaction time

Google has confirmed it has closed its internet drone project Titan, three years after it bought the business.
The drones were designed to bring the internet to remote rural areas, complementing its Loon project - a similar initiative using hot air balloons.
However, the solar-powered vehicles have faced technical difficulties and funding challenges.
On Wednesday, blog 9to5 Google revealed Titan had actually shut in early 2016.
A statement from X, the Google division responsible for Titan, confirmed the news.
"Titan was brought into X in late 2015. We ended our exploration of high altitude unmanned aerial vehicles for internet access shortly after," it said.
"By comparison, at this stage the economics and technical feasibility of Project Loon present a much more promising way to connect rural and remote parts of the world."
Google acquired Titan Aerospace in 2014, reportedly fending off a bid from Facebook, which has also been trialling internet-providing drones.

At the time Google said it was "early days", but that "atmospheric satellites could help bring internet access to millions of people, and help solve other problems, including disaster relief and environmental damage like deforestation".
However, after test flights began in 2015, reports alleged that Titan was facing technical difficulties and was running out of money.
In mid-2015, the Titan team also experienced a crash in the Arizona desert which was later linked to a wing fault.
The statement added that "many" Titan staff had been reassigned to different parts of the business, including Project Loon and Wing, a division dedicated to providing drone-based deliveries.
Facebook's internet drones have also faced problems.
The firm's Aquila drone crashed during a test flight in June, prompting an investigation by the National Transportation Safety Board, and an explosion destroyed one of its satellites earlier in 2016.

Parents worry about their children being bullied online, but what if it is your child who is doing the bullying?
That was the question posed by a BBC reader, following a report on how children struggle to cope online.
There is plenty of information about how to deal with cyberbullies, but far less about what to do if you find out that your own child is the source.
The BBC took advice from experts and a mother who found out her daughter had been cyberbullying her school friends.

Few parents would want to admit that their child was a bully but Nicola Jenkins has gone on record with her story. You can watch her tell it here.
"Nobody thinks that their own child is saying unkind things to other children, do they? I let them go on all the social media sites and trusted the children to use it appropriately.
"Our form tutor phoned me up during school hours one day to tell me that there'd been some messages sent between my daughter and two other friends that weren't very nice. One of the children in particular was very upset about some of the things that had been said to her.
"Her friend's mum spoke to me about it and showed me the messages that had been sent. When I approached my daughter about it, she denied that there had been anything going on. It took a while to get it out of her, but I was angry with her once I actually found out that she had been sending these messages.
"I spoke to her teacher and to the other parents, and between us we spoke to the children to let them know that they can't be saying unkind things and to just make them aware that whatever they do is recorded and can be kept. And they all did learn a lesson from it.
"I removed all the social media websites from her so she wasn't able to access them for a while and then monitored her input and what she's been saying to people.
"But it did make me feel angry and quite ashamed that my daughter could be saying things like that to her friends, but she has grown up a bit since then and she's learnt her lesson.
"You want to trust your children, but they can get themselves into situations that they can't get out of.
"And as they get older, they look at different things. I know my son looks at totally different things to what my daughter does, so it's just being aware of what they are accessing and make sure that they are happy for you to look at what they are looking at as well."

According to not-for-profit organisation Internet Matters, one in five 13-18 year olds claim to have experienced cyberbullying but there are few statistics on how many children are bullying.
Carolyn Bunting, general manager of Internet Matters, offers the following advice:
"First, sit down with them and try to establish the facts around the incident with an open mind. As parents, we can sometimes have a blind spot when it comes to the behaviour of our own children - so try not to be on the defensive. Talk about areas that may be causing them distress or anger and leading them to express these feelings online.
"Make clear the distinction between uploading and sharing content because it's funny or might get lots of 'likes', versus the potential to cause offence or hurt. Tell them: this is serious. It's vital they understand that bullying others online is unacceptable behaviour. As well as potentially losing friends, it could get them into trouble with their school or the police.
"If your child was cyberbullying in retaliation, you should tell them that two wrongs cannot make a right and it will only encourage further bullying behaviour. Stay calm when discussing it with your child and try to talk with other adults to work through any emotions you have about the situation.
"Taking away devices can be counterproductive. It could make the situation worse and encourage them to find other ways to get online. Instead, think about restricting access and take away some privileges if they don't stop the behaviour.
"As a role model, show your child that taking responsibility for your own actions is the right thing to do. Above all, help your child learn from what has happened. Think about what you could do differently as a parent or as a family and share your learning with other parents and carers."

Many critics blame social media for not doing enough to deal with cyberbullying. Abuse is prolific on Twitter and it has pledged to do more, including improving tools that allow users to mute, block and report so-called trolls.
Sinead McSweeney, vice-president of public policy at Twitter, explained why the issue is close to her heart:
"As a mother of a seven-year-old boy, I've always tried to strike the right balance between promoting internet safety and encouraging the type of exploration, learning and creativity that the internet can unlock."
She offered the following advice:
"If you find that your child is participating in this type of behaviour, a good first step is to understand the nature of the type of material they're creating, who is the target, and try to ascertain their motivations.
"If the bullying is taking place on a social media platform, make sure to explain to them why the behaviour is inappropriate and harmful, and to supervise the deletion of the bullying content they have created. If it continues, it may be worth seeking additional advice from a teacher or trusted confidant."
