it's an Engine2 limitation. Please use PIRC (per-interface rate control,
a subset of CAR) on this interface instead, i.e.

int gig1/x
 rate-limit input 1000000000 200000 400000 conform set-prec-transmit 0
exceed-action drop

the exceed action is a noop, you will never exceed the 1Gbps configured
;-)
