A half century of driving
Over a half century of driving, driving professionally for a time, driving a NYC taxi, driving long haul buses, commuting into NYC on motorcycles, etc. I have racked up 72K miles in one year.
I have never had a real life trolley problem involving people, pets, or vehicles.
Reduce speed when conditions become ambiguous. Be aware of the area your vehicle is entering. Constantly scanning for possible "targets".
Situational awareness. [Also useful to survive as a pedestrian in current year London.]
