Sure, you do 99.9% of the time. But all it takes is once, you're distracted, someone's yelling at you from the house, whatever, and then that's it.

And so that's the vehicle's responsibility? Like, you're complaining that a truck/suv has a 9-foot blind spot.

What's an acceptable blind spot - where if someone hits a laying down/sitting kid in front of their car, it's the driver's fault and not the vehicle's?
