Actually you can.
After all especially while Driving. You wont notice a Shift of a few Degrees.
You also wont notice when you Change the Area because the Adjacent Areas will be loaded in the Backround already before you reach it.
An General Tiles System.
Imagine it like a Chess Board.
You always have your Own Tile. As well as all Neighboring Tiles loaded.
You go to your Neighboring Tile. Now he Discards the Tiles which no longer Neighbor you. And Starts Loading the Tiles which now newly Neighbor you.
Since the Tile will be Loaded way faster than you could ever reach the Border on the other Side of the Tile you just Arrived it. You will not get any Loading Screens or Seams.
As I said.
Programming is often Trickery.
It needs to be Seamless Playabale for the Player.
That doesnt mean your not allowed to add any Seams in the Program itself
