Definitely agree, fast, cheap travel also makes more apparent the issue of scarcity in high-demand areas (e.g. the beach in Rio). Interesting to consider if those areas are actually less crowded because you can get to more alternatives easily, and fewer people actually live there permanently because they could live in the remote country side and just go there for the day.

Not sure how things shake out as these transportation trends evolve: do you still have a tendency to crowded areas, or do you actually end up getting more diffusion. Suburbs were the city planner's utopia for a long time, but traffic and feelings of lack of community ended up making them less appealing than originally imagined. Maybe the suburb approach becomes more compelling again if problems of traffic & lack of community are addressed.
