does anyone else thinks tech demo needs updating?

Hi. So i have the full version of the game and it's awesome, however, one of my friends uses the tech demo and he says that he don't really want the game cause from the tech demo, the game is like ror with less cars. So i think the devs should update the tech demo, make it features some of the latest stuff like: thermal, gps,.... And it could maybe make people want to buy the full game
So, what do you think?
