FWIW Cybertruck (and all other teslas) have a forward collision warning system that can detect pedestrians and automatically brake. Not perfectly of course, but better than other cars. Large cars are not the primary driver of increased pedestrian deaths in the USA, either.
Incorrect. Light trucks account for 54% of pedestrian fatalities compared to passenger cars at 37%. Impossible for more than half to not be considered the primary cause.
Every countries in the world got cellphones. Many saw a drop in fatalies on the road, others it went up (US). Cellphones surely don’t help and are awful but once you hit someone the size of the car (and speed!) matters on the outcome and cars are bigger in the US.
