Draw a bitmap partially off-screen

[neurino]

Immagine a car sprite moving on the screen from left to right. How do i draw the car XBM bitmap so that only the hood peeks out of the left border?

i.e. drawXBM(u8g2_uint_t x, ... allows only positive values of x, now what?

Negative values should work.
Depending on the current u8g2 configuration, -1 becomes 255, which will lead to the intended shift.
