What's the purpose of the Weeride Copilot "safety" tabs? I just bought a used WeeRide Co-Pilot bike trailer. It's pretty good except for one little feature(?)



These tabs stick out on the side, and I'm assuming they're safety tabs to help you not run over your child, but for the life of me I can't figure out why. If I try to make a low-speed turn in our road (about 16') it will twist my seat around. It's less maneuverable than my regular bike trailer due to that fact.

Is there any real reason that I shouldn't follow through with my plan to grind them down/off so I can make turns safely?
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.
