I agree, but how is this different than a tank drive? If you lose one side of the chain you're pretty much stuck (although you can do a funky circle). In my experience the chain typically fails at the connection point (master link) and with a long chain there will be a few more chances for failure because there are a few more master links. If inspected periodically this should not be a major issue. You can also get 50' or 100' lengths of chain at McMaster
