As always, keeping the battery fully charged will minimize the chance of a Jaguar browning out at ~6V. I'm confident that teams using the advanced CAN features also know to check for the "I just powered on" flag so they can reconfigure the reset Jag.

That won't be a problem for veteran teams, but I think there will be a good number of teams who try CAN for the first time without considering a Jaguar reset. To be honest, if I had not heard of that issue, I wouldn't have thought of it either last year when I experimented with CAN.

Ideally, a team would manage their own current limiting with CAN, but for many teams, a stall will certainly trip breakers. (although if they trip them while accelerating normally, that is definitely a design problem)
