It's also worth noting the current speed limits were set in 1985. I know this is the wrong place to point it out, and I do hate cars, but acknowledge they have value for some use cases. That said...
Since 1985, car safety evolution has introduced: -Traction Control -Anti-lock Brakes -Airbags -Electronic Stability Control -Crumple Zones -Adaptive Cruise Control -Blind spot detection -Pedestrian detection
...just to name a few. Cars are safer now than they've ever been, for both drivers and pedestrians (the Cybertruck not withstanding), so it's equally strange to suggest that the same speed limit that was set in the mid-80s is the best balance of convenience and safety. If it's simply a matter of reduction in absolute terms, why not LOWER the speed limit?
Not saying the article's premise is wrong, but it's kneejerk. In fact, smartly using speed limits can help to push traffic into out of the way areas where it will be less problematic to pedestrians. For example, lowering the speed limits in pedestrian areas in cities and increasing them less dense, outer areas can both improve traffic flow and make dense spaces more pedestrian friendly by diverting traffic into roads with fewer people. And intercity traffic through areas with little to no pedestrian traffic is a no-brainer.
If cars are safer for pedestrians than ever, then why are pedestrian deaths increasing?
Number of cars. Increase the number of cars, you increase the number of deaths. But any given collision is more likely to be survivable than in the past.
Also, it's not a perfect analog, but a quick search for deer hits and you can see modern cars crumple just fine.
Don't get me wrong... I'm not saying this deer was out dancing that very night, but if you're gonna hit me at 30 MPH with either a flat, unyielding piece of steel with potentially sharp edges and/or rusted spots, or a soft piece of plastic or fiberglass formed to cushion my impact into the engine where the REALLY hard parts are, I'm going to choose the plastic/fiberglass every time.
Edit: Here. Just to back up the information I'm giving you...
The ABSOLUTE number of deaths are increasing, because the number of people and cars are increasing. But as a function of percentage of population they are only slightly above the lowest they've been since the 20's. Modern cars are much safer. Even a bad SUV with horrible visibility is safer to all involved in a crash than an average car in the early 80's. The numbers don't lie.

Edit again: To give pedestrian numbers to go with that:
You do have a point... there ARE increases in recent years, but overall the rate is still nearly half of the rate in the 80s. You are correct the most very recent trend is worrying, however.
