Where to set down the button area in a 10.25 Inch screen?


I am designing a layout for a 10.25 Inch(1920*720) car front screen, The application helps taxi drivers to pick up passangers who use a app to call a taxi . The screen consists of a button area and a map area. I think if I put the button area in the left screen may help drivers touch them easier, but my parter thinks it is right to put the map area on the left for easier observed .
What do you think?


Forgot to mention: in the car the driver sits on the left side
