 =========== BUGS =================
 
+- sometimes the games prints huge long ass number of newlines, WHY (happens
+  when driving on accelerator)
 - immediately after starting the map countdown seems to be lower
 - the pinch collision test seems to sometimes stop the car e.g. after falling
   from bigger height or when running into ramp at high speed (or not?) - FIX
