I disagree with your claim that cars will be gone, as the rare non-SUV owner (and as someone who also answered parent to argue.) Cars don't cost that much when you drive reasonable cars for occasional trips. They're expensive, but certainly not as much as, say, food. When there is enough momentum to push most cars out of town centers and to slow those not removed (10mph is ample to do the heavy lifting which should be the domain of cars), there will still be a place for asynchronous, on-demand high-speed travel. It will probably be a return to the family car for those with families, and other efficient arrangements for others. When that happens, the relative free-loading of tractor trailers on interstates will be more exposed, plus the big box stores won't be as popular without daily car trips for all. By some highly suboptimal taxation scheme, we'll push logistics off the roads, except, once again, for high value uses where asynchronous, on-demand roads are worth the price. Edit: I learned that the 2013 Odyssey is 19lb. over the minimum GVWR, so I am, in fact, a truck driver.
