1. I think that cars have improved and made our life's easier because with their help we can get somewhere faster and more comfortable.

2. On my mind people need to choose best way for them. Traveling by car is quite comfortable, but really expensive because of fuel. Traveling by train is long, but comfortable because you can rest while traveling. Traveling by plane is the fastest way, so it's easier to travel like that if you are restless. Traveling on bicycle or foot is hard, long and boring, you are getting tired in few hours .
