It&#x27;s because Europe doesn&#x27;t do suburbs and parking lots the same way that America does. Densified development around transit services will result in more people taking those services. Less and&#x2F;or more costly parking in the city centre will result in fewer people driving. This is how Europe does things.<p>Basically, the mix of vehicles (cars, trains, driverless cars, whatever) is far less deterministic than the urban development patterns. Build suburbs with homogeneous lot sizes and city centres with a lot of free parking, and the mode choice is more or less a foregone conclusion.
