E.g. you drive on a road designed for relatively high speeds say 80-100 km/h. They decide to cross it, despite it not being a safe zone for crossing. You hit the pedals and swerve off the road injuring yourself (or you get rammed by a vehicle behind you).

Injury =/= death. If you swerve off the road, you have airbags. If a car behind you hits you, again, you have airbags. You have tons of metal shielding you from a collision, insurance that is supposed to take care of the situations that can't be blamed on you, and airbags and seat belts that are supposed to reduce the consequences of a collision.

Pedestrians have none of that. Where I come from, this (alongside first-aid skills) is the very first thing you learn on your way of getting a driver's license, before road signs and traffic rules are even mentioned.
