But the system gauges my value judgement poorly. I never made judgements about whether swerving was a factor, but it gave a gauge on that. I considered the passengers living with witnessing smashed bodies on the windshield (all else equal).

Also, even with no difference (or more death ahead), braking and scraping into the wall "left side from observer" drops more momentum safely and allows crossers more time to move forward along their momentum (although I didn't specifically use that because it was against the rules).

There is no way to make an optimal decision in this game.
