Dirtbikes, ATVs are better at traversing the terrain and we wouldn't need roads. If you want to get anywhere you need to go fast. The problem is speed kills. Even with all of the gear it's significantly safer to be a two ton steel cage. Personal helicopters would be ideal but that seems cost prohibitive and amateur flight isn't legal. The allure of the car is independent transportation. I suppose self driving cars would help the safety issue if they work but they still need roads.
