Yeah, but there's only so much technology can do to mitigate a 40mph impact.[1] And I assume that 65 Toronado required wide turns (as did the 60-something Pontiac Boneville I briefly owned and stupidly sold because it wasn't sleek enough). Whereas pedestrians getting clipped by a left-turning car racing pedestrians is a regular occurrence.
That said, point taken. And those mitigations are based on real-world data, not my anecdotes. And, of course, nothing prevents us from having the best of both worlds--safer cars and safer streets. I was just thinking that streets are so stupidly designed today because, once upon a time, the same configurations may not have been as stupid. (I know that one reason SF streets are so wide, especially in the Western part of the city, is because they were designed to accommodate street cars and cars simultaneously.)
[1] Automatic braking is a huge deal but its far from pervasive. The last time I went car shopping three years ago, it was still an expensive option for both the Honda CRV and Mercedes GLC we were looking at. My lease is almost up and I think it'll be standard on the same model CRV. Even when it becomes standard industry-wide it'll be many years before I'd factor it into my mental calculus as a pedestrian. Less well-off drivers in older cars spend a disproportionate amount of time on the streets simply because of the economics (e.g. often live far outside the city because of housing costs, and drive into the city because neither their homes nor jobs are conveniently located to mass transit).
