ReferencesIf you observe carefully, it's possible to see some blank (and a lot of grey too...) letters behind the official car (a flying vehicle responsible for recharging its power meter), where is written something as "PIT-TIP" (but the P letter of the word TIP is inverted!). To see this, open an official car captured screenshot (an emulator is recommended) with any image editor and use the zoom-in effect (if available) in the middle square area with black and yellow lines: you will be capable of identify these words with a lot of attention.
