The reason that the WitStar comes with a fish tank is to prove just how safe autonomous driving can get. Guangzhou Auto believes that a crash would no doubt result in the fish tank shattering, so if you have a fish tank within, all passengers in there should have a sense of relief and safety, or so the line of reasoning goes. It does make me wonder whether there will be a separate battery to power the filters and air pump in the fish tank, at the same time finding a way to keep the water inside cool even when you are parked out under the scorching sun for hours on end so that your fish will remain alive after you have completed a hard day’s work.
