There seems to be confusion regarding the entrance and exit gates. The entrance gates require the use of the gate pass to raise the gate. Tailgating through the gate to avoid using your own pass is unsafe as carts crossing have to depend on that short delay to cross the street.

The exit gates are controlled by a sensor buried in the road surface that detects the presence of a vehicle to raise the gate. The gate will stay up as long as there is a vehicle present to trigger the sensor. For the exit gates, you do not have to wait for the gate to come down from the vehicle in front of you to pass through. In most instances, carts waiting to cross can see the traffic exiting the gate and know when it is sage to proceed.

Stopping to wave a cart across instead of proceeding creates an unsafe situation. Even though it appears courteous, it sends the wrong signal to cart drivers who may expect this is standard procedure and pull out in front of a vehicle. It also creates a surprise for vehicles behind who don't expect you to stop when there is no obvious reason to.

I can understand that when the exit lane is backed up from the roundabout through the gate that it may be courteous to allow cart traffic to cross rather than block them, but that is the only time it may be appropriate to do so. Remember that the cart is still at risk from traffic entering the gate.
