Getting into and out of vehicles, especially those with low, sporty profiles can be difficult.
Today’s invention is seats which detect if anyone is sitting on them and which can be driven forwards or backwards, when the vehicle is stationary.
When a front door is opened, and that seat and the one behind are empty, it will slide back to allow easier access.
Similarly when a back door is opened, if the seats on that side are unoccupied, the front one will slide forwards.
