How has the introduction of the automobile and, subsequently, the highway begun to fundamentally change the way cities are designed and function?

Answer:

The introduction of the automobile and, subsequently, the highway begun to fundamentally change the way cities are designed and function because these technological advances have allowed citizens to travel greater distances in less time: before the automobile, the horse was used to get around, which travels distances at about 30 kilometers per hour on average, and needs to rest after long stretches. Today, the car travels at average speeds of about 60 kilometers per hour and does not need breaks, other than the logical routine mechanical conditioning.

Thus, cities have been able to begin to expand horizontally, enlarging their contours because people no longer necessarily need to live near their centers, thanks to the mobility facilities that exist today.
