 In my system, there is no significant change on speed when Karts are there or 
not. I have FPS disabled (how can one enable them?), but I can't really tell 
the difference. Of course, in other video cards - especially the badly X11 
supported, like ATI - there might be significant lag when a few karts are 
visible.
 But the slowness that occurs after a while (I don't even have to drive, just 
to stay there) is surely the responsible of some bad code.

 Anyway, maybe the best solution would be to have a Karts detail option in 
Graphics Options, and one could change between both versions of the cards: 
the one with lots of polygons and the other with fewer.

 It is also good to know that textures can help - haven't remember of those -, 
but ugly stuff like those heads made of squares will not be helped:

sometimes aborts.  I have followed the rules of programming, yet I am totally
baffled. What is the reason for this?"
	The master replied: "You are confused because you do not understand
the Tao.  Only a fool expects rational behavior from his fellow humans.  Why
do you expect it from a machine that humans have constructed?  Computers
simulate determinism; only the Tao is perfect.
	The rules of programming are transitory; only the Tao is eternal.
Therefore you must contemplate the Tao before you receive enlightenment."
	"But how will I know when I have received enlightenment?" asked the
novice.
	"Your program will then run correctly," replied the master.
