Today’s invention is a car designed with tourism in mind.
It has a bank of rear seats which can be driven upward through a giant hatch in the roof, so that occupants can see more of their surroundings and take photos unimpeded by glass windows.
The seat height would be variable and rising out of the cabin would only be allowed when the vehicle was travelling below a certain speed. Sensors would detect eg low bridges.
In the autonomous vehicle future, this will provide occupants with a new way to pass the time on boring journeys.
Adventurous users could select a maximum height of say 4m and drive through safari parks.
