text: I believe in weird landforms because it would make since that they would get there from either destrution of something else or creation of another landform. But why doesn't NASA send a space rover to mars to scan the face and collect some samples from it?Self driving cars. Everybody wants a car that can drive itself, but is it really practical? Many people say that self driving cars are a thing of the future, while others argue that they should not exist. Autonomous cars are not practical and should not be on the road because they are dangerous, impractical, and boringly monotonous.
