I live in London. Most residential streets are two-way but there is only space for one car, and driving on the curb is not really an option.

The trick to UK streets is that parking actually happens on the street itself, and when driving you must find a spot when people are not parking to make way for people coming the other way.

> Stevenson St is a two way road

That is extremely narrow, I wonder why the city has not designated it as a one-way street? They've done that for other similarly narrow sections of the same street farther north.
