Walking mechanisms

A walking scooter for disabled persons was one of the first applications of walking mechanisms. The walking scooter could walk over curbs and up and down stairs. This was a great advance, because a great many more places became accessible to disabled people. Eventually, the technology was applied to automobiles, so that by the mid-21st Century, cars could walk over and set themselves down in a small parking place. They could get out into the street the same way. A more extreme version, that is frowned upon by the authorities, allows a car to get up on long legs and step out of traffic jam and walk over the grass on the side of the highway to the access road. Talk about modern conveniences, yes?
