Lol! As you know driving an automobile in London will drive you mental in addition to the cost. Also, a lot of the city is walkable. It takes about 40 minutes to walk from Buckingham Palace to St. Paul's.

Shameless plug: You might enjoy some of my observations on British and English life posted here. There are several. I spent most of the 70s in the UK (Abingdon School and Oxford) about a week out of every month between 1997-2008 and 2017-2021.
