250 C is over 480 F. Even if it could somehow get up to 250 F inside a
car CD player (way more than hot enough to boil water, and the parts of the
car in direct sunlight would have to be much hotter) it would still be 230
degrees colder than the melting point of polycarbonate. Usually, warping or
bending points are relatively close to melting points. I doubt it would
ever get up to 250C in the CD player, even in the middle of the Sahara on
summer solstice. Heat radiation and convection of the air (even if the air
is 130 degrees) would be very significant. But even if it did, the CD is
still 230 degrees cooler than melting point, so it probably hasn't even
started to soften at that point.
