This article is a bit sloppy. Just because we use our cars 5% of the time does not mean we only need 5% as many self-driving cars. That assumes there is no overlap in when we want to use them. Also, all those words and not one mention of the liability shift to the manufacturer when cars go fully autonomous. That's one of the biggest issues with the transition. Software will have to be near perfect to avoid bankrupting manufacturers through tort suits. (It's not just an insurance premium shift, it's liability for major tort damages in fatal accidents that often bankrupt the responsible party.) So we are more likely to be in a semi-autonomous, driver-assistance world for quite some time. And that invalidates pretty much all of the article which is predicated on driverless vehicles.
