Hi, Randy,
The reason you're not allowed to create a variable named "x" is
because all players already automatically have a system-defined
variable named x -- the horizontal cartesian coordinate. So "Car's
x" would become ambiguous if Car, in addition to having its built-in,
system-defined variable named "x", could also define its own "x"
variable.
Cheers,
-- Scott
