As a European (dutch), why are our roads so small, that normal sized cars look like "monsters". I have often thought, that Europe will have a problem in the future with roads, as they are just too small, and expanding and making them more safe, is unlikely to ever happen and often times impossible. Not everyone can get by with a small little hatchback, some of us need a big pickup (I own a building company). And for the people that do not need it from a commercial point of view, have you ever considered that people have hobbies and some hobbies needs a fair amount of space in a car? Or families with multiple kids doing sport need the space for all the gear? I am worried that in the future, more and more european cities will just address the problem with a disguised "we are making the cities car free, and thus greener and safer". What that means for the average citizen out there is, that any building related work, will just become more expensive, as people will just charge more to get over the hassle of getting into the cities then.
What I've observed, is that 90% of journeys people make can be done without a car.
Designing a city that helps people make those journeys car free, makes it better for the 10% of journeys that do need to be made with a car.
I'm glad the roads are small. Smaller roads cause slower driving (well researched). As for the cities, it is unsustainable to use cars as the primary mode of transportation within cities. We do want to make cities greener and largely car-free, because cars for individuals simply do not make any sense in a city. We still need roads for deliveries and occasional transportation of heavy or large goods, but transporting yourself within a city should rarely be done in a car. See Tokyo for an example of a large metropolis which functions well and which would completely break down if everybody tried to use a car to get somewhere.
