Your attitude that all accidents you are involved in will be the fault of other drivers, and that they will therefore deserve the lethal consequences, is a truly bleak data point. What about a child who darts into the street, who you have no hope of seeing because your vehicle is so tall? What about the cyclist who has a moment of inattention and ends up plastered to your grille? Is death the appropriate consequence for their actions?

None of this is necessary; people can and do live in a better way in other places. Japan has fewer than a quarter of the traffic deaths per capita that the US has.

Prisoners dilemma illustrated : you choose what you think is the optimal solution and end up with a degraded situation for everyone (including you).

The paper actually does not show that. It might well be that increasing weights of all cars 2x decreases fatalities 10x without changing relative fatality chances between cars with different weights.

People like you are the reason we can't trust people's judgement, why we need to take that choice away with laws.
