> Increasing travel times and inconvenience isn’t a win and safetyism is irrational.

By very narrow definitions of win. Perhaps more time in transit is worth fewer deaths and less pollution. (I rode a bike daily and year round in northern Ohio for 8y.)

> If you can’t make fast driving safer you haven’t achieved anything really.

By what measure of achievement? Zero traffic deaths in a heavily populated city is quite an accomplishment IMO. But I'm not a racecar driver so maybe I'm unqualified to judge.
