The Story
Cars get cleaner over time due to federal regulation and technological improvements, although the number of cars on the road increases because of population growth. Driving increases to 86.4 million miles per day across the four-county Wasatch Front. The percentage of electric cars, which produce zero tailpipe emissions, stays at 1%.
