Here are a few reasons: Cars still pollute - dust from tires causes harm to lungs and streams and is contributing to the decline of salmon populations. Cars are heavy, damaging roads, increasing maintenance costs compared to electric bikes or public transit. Cars are large, and need to be parked. That means larger roads and more parking lots, rather than using the space for housing, businesses, or parks. Bikes, buses, and trains don't have the same problem. Cars reduce access to cities - highways and arterials are difficult to cross, and divide neighborhood activities. Cars are dangerous, humans are generally only moderately adept at driving them. We have tons of injuries and deaths because people are bad at driving. (Or have to drive when they shouldn't.) Cars are inefficient. The energy used to move 1 person via a car compared to any other form of transport is one to two orders of magnitude higher. Cars require distributed energy rather than the centralized infrastructure that public transit requires, which means many small chargers rather than one electrified rail. Cars aren't affordable for everyone, leading to inequalities in who is eligible to work at certain jobs. There are probably more reasons, but cars are a deeply inefficient and costly means of transport.
