What changes were necessary as the automobile replaced the horse and buggy?

The transportation infrastructure had to change dramatically to accomodate motor vehicles rather than horses and buggies. Some examples include:

1. The roads had to be updated from packed dirt/gravel or paving bricks to solid sheets of concrete or asphault - the suspension systems on cars moving at higher speeds would break down on the earlier road bases, and the new vehicles wore out the road surfaces much faster.

2. Laws and regulations regarding the "rules of the road" had to be developed - when you had horses going 10 mph there weren't as many problems, but as speeds increased there needed to be a common set of rules to reduce accidents and injuries.

3. Licensure had to be developed, since motor vehicles were much more likely to cause injury or death if mishandled.

4. Filling stations, repair shops and other vehicle service stations had to be developed to provide needed fuel and mechanical assistance.
