What's the purpose of the Weeride Copilot "safety" tabs?
I think the only real reason why you shouldn't remove them is that if you're moving the whole thing (without anyone on it) and it violently crashes against itself (say you pick it up to store it and it slips) then the safetly tabs will take the damaage and potentially save the rest of it. 

Apart from a case like that, if you're safe with how you use it, the safety tabs can be removed.
