Yea, but same could be said of any attraction really.. And it couldn't be any worse than Mummy or Gringots where if the system senses anything on the track (even if there's not actually anything obstructing) the ride vehicles can no longer move and must be evacuated (which has happened to me twice on each ride now).
One would hope that UC's version of trackless would be a bit better than Oceaneering's, as far as comms go anyway, but with new technology comes new issues.
