Trips that take me 3 hours in normal traffic here would take less than 45 minutes in China... possibly as little as 30 minutes. Trains would be leaving for the main destinations in 15 minute intervals, travel times cut by an order of magnitude, arrivals would be in stations that connect to clean, modern, efficient, inexpensive and safe subway systems.
A typical journey. Hangzhou to Shanghai used to be a 3 hour bus ride for me. On top of that it was 45 minutes from home to the bus station. Now I can walk a few hundred meters to a gleaming, state of the art metro station (seriously, you've never experienced anything like this if you've never left the US), arrive in the ground floor of the train station, catch a glass smooth, spacious high speed train to Shanghai that leaves every 15 minutes and takes only 45 minutes and go downstairs to the subway to travel wherever I need to go in the city (usually within a couple of blocks of whatever destination I have).
We are so far away from this that I find it a bit distressing. We cannot afford it, we cannot overcome the legal and political hurdles to make it happen... we are just going to fall further and further behind.
