   Stealth does use a RAM for *reducing* detection by radar. However,
   what gives it the "stealth" ability is not that, but the fact that
   the aerodynamics of the planes on the aircraft are such that no
   radar is reflected back to the originator. 
   Now, if the question was to make it radar proof by changing the
   shape of your car, then I agree it can be done. But if you expect
   to get immunity to radar using RAM, dream on. You will certainly 
   get a reduced return from such cars, but as I pointed out, it takes
   only a windshield or a head-lamp lens to get an accurate enough 
   reading of the vehicle speed.

   So let me ask you your question. Do you have any idea how Stealth
   aerodynamics work?
