Concerns about the environment have increased over the years, and recently, some have stated that fossil-fuel-based cars should be banned and replaced by electric ones, leading to intense discussions. I disagree with this very extreme measure. Fossil-fuel cars still predominate over electric cars these days. Prohibiting people from using these would generate two significant problems. First, people would have to figure out what to do with their previous vehicles. Second, most countries would not be able to support such a large-scale change.
