The future of car ownership that no one is talking about

Not a great article, but still a topic worthy of discussion. I do assume that starting in a few years that the average number of cars per household will begin to drop towards zero. Clearly this has huge implications for the economy since the automotive sector, including, financing, insurance, aftermarket parts, maintenance, etc. is amongst the largest sectors of the US economy.

I still think that it will be a net positive, as people will spend less wasted time in traffic (since they're not driving, the time can be used), and the number of accidents will drop considerably. But still, we're in for some painful adjustments.
