That would be me, and I disagree.
Using canned air to cool the main breaker is actually very effective and not unsafe or misuse. If they do make it illegal it will not be because of the unsafe nature of spraying canned air but instead because of the possible unprotected surges of current. I think it is much more likely that the use of a fan on the breaker will be made illegal.
That all being said the most effective way to prevent a breaker tripping is having a properly trained driver or having automatic shifting. I say this because often the breaker will trip when the drive train motors are both stalled in high gear. A driver who downshifts before a collision and does not rapidly change from moving forward to backward will not trip the main breaker. I would be wary of the current sensing limiting the driver train because it takes control away from a driver and has a high chance of failing.
That being said if you are going to sense current, you should make your own sensor instead of using the built in sensors in the power distribution panel. This is because from my understanding the power distribution panel only has current sensing on the outputs and not the input. You should put the current sensor on the main pole of the battery, it should also be inductive instead of resistive. I made one last year in twenty minutes with parts that cost 3-4 dollars.
