Thank you for your feedback!
I've added an alternative control scheme for keyboards without Numpad in the minor update (v031) i just released. See the help page (F1) for more information.
However the mouse positioning problem could be part of a bigger issue. Since you are on a laptop, am i right in assuming you're running a resolution lower than 1920x1080? Unfortunately, for now i only can support at least this resolution. I'm planning to make my UI system more flexible, though.
With your resolution are you able to see the bottom white border of the world view and the 'Hint status bar' below? The Hints will only appear when they're triggered by certain actions, for example accelerating your car.
