My invention!

If i were an invetor i would invent a shoe that got an engine so you don´t have to walk. Everything would be so easier. You don´t have to take the bus, drive your car take the train... You could walk as fast as the train, bus and your own car. I would put the engine in the bottom of the shoe an it´s a small engine. Small as a little chip. I would have brakes to.
The brakes would be at the back of the shoe so you just have to take up the front of your foot and then the engine will stop working. You may wondering how to start it. You press a bottom and the engine will start working. You can go from Sweden to Denmark. Thats my invention.
