Comment The coral will need guard rails around it (Score 5, Insightful) 76
A tourist with 30 minutes of training piloting a sub near coral reefs is a bad idea, the pilots will be looking at all the neat things and not paying attention. Depending on how powerful the currents are they could get swept out and run out of fuel fighting the current. These things are far from idiot proof and you should expect drunk or stoned college students on spring break to be using them. It's a great idea until you realize you are giving dumb-asses a $1.5 million dollar vehicle to drive through priceless and breathtaking wildlife sanctuaries, while we are at it let's start renting out Bugatti Veyrons to drive through the Louvre.
