This is it right here, a similar analogy this brought up was car manufacturers of old making an excuse that fatalities were the idiot drivers fault and not because of the inherent lack of safety features of the vehicle. It's too damn easy to make the wrong assumption in C & C++ and spend a painful amount of time debugging.

In my experience the added safety guarantees have made me more comfortable in "going faster" and back to vehicular terms the choice is still there to not fasten the seatbelt and go `unsafe`.
