Ever been cut off in traffic? Ever got a speeding ticket? BJJ is very much like driving a car but there are no speed limits, very few rules and almost no-one has insurance.The difficulty with BJJ is the driver and car are one. If the coach has not outlined the terms and conditions on what the rules are then it's hard to be mad at people going super hard if that is not breaking any rules.
Communication is key to make sure that team mates know what kind of a roll you came for you may not want the Fast and Furious experience. No matter how you like to drive your body must be robust because physical strength and flexibility is your insurance policy.
