- The streets in London are smooth. I didn’t see a single pothole or patch.
- The Underground is more than 100 years older than DC’s Metro. And it seems infinitely more reliable.
- Underground trains come every two minutes. There is no crowding on the platforms because there’s no time for a crowd to accumulate.
- With that level of train frequency, why would you ever want to drive?
- I wonder how many billions of dollars we could save if DC’s Metro trains ran every two minutes.
- Horn honking in London is not much of a thing, mostly because drivers seem to obey the rules. (Truer still in Stockholm.)
- I didn’t hear anyone cuss out a cyclist in my seven days. They often use bus lanes and the bus drivers just go with the flow.
- Bromptons are very popular in London.
- Bike theft is apparently a problem; people lock their bikes with serious hardware.
- People in London walk fast. They seem to be underdressed for the temperature.
- I have yet to figure out if walkers should stay to the left or the right. When on an escalator, you stand on the right.
- Footbridges across the Thames are the best. They seem to be about the length of the Key Bridge between Rosslyn and Georgetown.
- I don’t quite understand why the platforms and the train floors are not at the same level. “Mind the gap.”
- You can actually understand the announcements in the tube stations and on the trains. I wonder if they could send someone to DC to teach Metro personnel how to pronounce “L’Enfant Plaza”.
- Curbstones are not nearly as high as in the US. And the buses come right to the very edge of the curb.
- I’ve now been to five left hand drive countries. It still confuses the hell out of me.
- I was hit by a wrong-way cyclist on a one-way street in Boston when I was in college. I now look both ways all the time, regardless of traffic flow. Without this I would have been roadkill in London.
- The entire time we were in London, the temperature varied only about 10 degrees F. And it was warmed than DC despite being at the same latitude as Labrador.
A Few Spokes Shy of a Wheel 
Interesting cultural differences. Any photos? I featured your blog in mine, hope that was ok.
Just some over on my Flickr account. (Look under Rootchopper). Thanks for featuring my blog.
We drive on the left side too (Australia). Driving on the right scares me rigid.
