Do you REALLY need 360 different angles for your images, though?

I mean, why stop there?  Why not allow the car to move in fractions of degrees?
Have 720 different images?  Or 1440? :^)

For most 2D gaming purposes, 16 or even 32 or 36 different angles of your
images is _plenty_.

At some point, your sprite is so small that the 91 degree and 92 degree
images of the car are indistinguishable.
