You’re right, mass use of roads for everyday transportation is incredibly inefficient in almost every way: Outrageously high construction/maintenance costs, outrageously large space requirements for roads and parking at both ends, high resource and environmental costs for the cars and driving per se, high costs in human health from a sedentary lifestyle and plenty of local pollution, high costs in human time spent driving around in cars, etc. We’d be much better off if we re-planned the whole society to switch as many trips as possible to other methods of transportation. This would require changes in land-use laws, a shift in investment toward mass transit and pedestrian/bicycle infrastructure, etc. Making the roads we already have safer would be a good start though.
