I've got a mixed opinion on suburbs in theory. In practice they suck utterly, yes. With a couple of tweaks, the idea can work, though. What makes suburbs suck is largely the lack of walkability, forced by zoning usually. Mixed-use retail / office / residential mini-downtowns, sensibly sized (ie small) no-car zones coupled with underground parking, transit hubs -- scatter those every half mile, and suddenly it makes sense to leave the car at (or near) home for a good long time. You have reasons to interact with your neighbors, &c. After that the biggest problem with suburbs becomes the horrible curse of acyclic road layout. Grids are good, honestly.

re: freeways: I figure we're less than 20 years away from workable computer-driven driving systems that let freeways run at 4x their current capacity, provided there aren't too many dumb cars in the mix. You can do things like intelligently redivide lanes into eastbound and westbound in realtime, run bumper-to-bumper at 70 mph, make way for emergency vehicles without slowing down, stuff like that. My point being that once that happens, there will be much less need to widen the freeways -- although there may be some transitional demand for 'no manual driving' roads and 'no automatic driving' roads.

when auto-driving becomes commonplace I think the next step is a blurring of the line between taxis and car rentals. Why drive yourself on a commute if the car can do it for you? and then: why own a car if you can have a perfectly good unmanned transport show up at your door every morning? (and the flip side: why keep your car in the garage when it could be out renting itself to commuters?)
