Do you park your car in your garage?

The answer is "No" for  most people for reasons which the above photo illustrate. It's not the blog's garage, by the way, though you aren't getting a car in ours either. However, here is some interesting technical data from a reader which again raises a question whether planners are up to speed on the size of modern vehicles. 

Houses with older garages might have been built when the average car was Mini or A30 sized (and) there are physical limitations to being able to put modern cars in such garages.
I'm not sure if there is a British Standard Garage but its bound to be smaller than the US equivalent. No doubt new build houses will have the smallest garage size & door that they think they can get away with.

Typically garage door widths were 7' wide though 6' 10" was possible. Today max width in a single garage door is 8' – 2,438mm

Because of improvements in side-impact protection, modern cars have become wider and also have larger wing mirrors to boot. Some "small" cars are in fact over 2m wide. You might just be able to squeeze the car through the opening with care, but unless the garage is well designed with space inside, you might not be able to open the doors sufficiently to get out! (particularly if you are broad in the beam).

"Broad in the beam". I liked that last comment - again, how far are planners allowing for the increase in girth of the average British person in the last 30 years? All the surveys suggest there has been a marked increase in "side protection".
