True, CAR drops packets that exceed the predefined limit. As Vincent says,
GTS (Generic Traffic Shaping) adopts to the bandwidth requirements (or lack
thereof), and modifies the situation so packets are not dropped, but
perhaps, delayed. 

You can use GTS with ACLs, with the 'traffic-shape group' command, with an
ACL and the capacity as arguments. GTS can also be used on frame relay
connections. 

Note that traffic shaping is not supported with flow switching.
