Agreed! I think the statements regarding interference are highly overstated. Take a look at this statement form Maxibotix especially item number 2(

1. "I was wondering if you for see any potential problems with other robots using the same sensor at the same time during competition?"
Great question. It is possible the MB1010 sensor may detect other sensors in the same vicinity. but it becomes very improbable as targets are closer to the sensor. For example, if looking at a wall that is 3 feet away, the time of flight for the sonar travel will be 5.3mS (calculated using 148uS * 36in), and another sensor operating close by might get picked up about 11% of the time. (calculated using (148uS * 36in)/49000uS ) And as distances get longer, this can occur with a higher probability.
2. "How can we be sure that the signal we get back is from our sensor and not from another sensor on another robot on the field during competition."
Another great question. If you use the RX pin to command the sensor to range at something other than it's default read rate, or even at a random time (you would use a pin from your controller to do this), and then one checks that two readings in a row agree, it then becomes almost impossible for the two readings to agree unless it is from a valid target.
