I think having unique houses gives neighborhoods character. Also, I wonder what they will do about security, seeing as if they make it the same in all of the houses, you only need to break the system once before getting full access to everyone. (assuming it's done centrally like everything else mentioned in the article.)
Robots, unlike humans, do not all share the same basic build. While a human could conceivably learn from another human's experience, robots would likely need something a lot more complex to achieve the same functions between two peers.
To develop a relationship between the two is difficult at best due to all of the factors involved.
One might take the gender of gamers into consideration or try to measure the impact of one game versus another, but in the end, you still have to deal with additional factors like what sort of information people take away from games and actually apply to real world situations as well as what really qualifies as a good decision in traffic given multiple factors. I think it is better to slowly pick out the effects of gaming on individual measures of "driving performance" before coming to something as grand as a definite relationship between driving and gaming.
That's just me, though.
