Wouldn’t it save you so much time if you could make your journeys by rail or plane by just jumping onto the train or aircraft whilst it was still moving at high speed, when it passed nearby where you lived? No need for it to slow down, or land, wait for people to board and then get up to speed again? You would save all that extra time and trouble of travelling to the train station, or the airport, going through security and queuing up to board? And whilst you were travelling at high speed wouldn’t it be fantastic if you could see much more detail in the scenery you were passing by, or flying over?More
