If you see her texting and driving what will you do?

Take her out back and shoot her, obviously.

Driving and texting in a full size car or a crossover isn’t any less dangerous to pedestrians than texting and driving in a truck. Full blackouts (the effect of driving and texting) means full speed hits and reduced visibility is irrelevant.

Full speed hits are a greater threat to other people when you're in a larger vehicle. More mass means more force to impart at the same speed.

technically yes, but the effect of more mass in a vehicle-pedestrian collision is asymptotic. a small (3000 lbs) sedan is already 15-20x the mass of a typical human. the vehicle loses a very small fraction of its initial velocity to momentum transfer. it really doesn't make much difference if you double or triple the mass of the vehicle.

try playing around with a momentum calculator to see what I mean: https://www.omnicalculator.com/physics/conservation-of-momen...
