It is unrealistic to expect this lifestyle in the long term. The era of the car will come to an end, likely in the next few decades. The personal car is a profligate use of materials and energy. We can afford them at the moment only thanks to market distortion and a massive one shot energy surfeit. When the real costs are priced in, very few people will be willing or able to pay. Had the real costs been priced in from the beginning, we might not have designed an entire way of life around them.
Your cookie cutter neighborhood (mine too) depends on circumstances which are unlikely to last. I say this with the utmost respect, and as an SUV owner!
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.
