Yea, 3 year suspended license. I'm sure when she can drive again at 83, she'll be a better driver. Honestly the standards (or lack thereof) is insane. People should be regularly tested regardless of age to see if they're competent to drive.

there was really nothing about the street or traffic design that was the problem

Someone died. There is something wrong with the design.

The driver was going so fast

The street was designed, actively or passively, to allow the driver to travel too fast.

it literally obliterate a steel bus stop

I dont know about this specific bus stop; but in my quick search, the different types of SF bus stops i saw all had sheer bolts. That bus stop may have been literally designed to sheer away from the pavement to reduce damage to cars and/or surrounding infrastructure, an interesting design choice based on what can be inside them.

traffic design had nothing and will do nothing for what happened in this instance

Check out "killed by a traffic engineer" and/or "confessions of a recovering engineer." It might feel like there was nothing wrong with the design; but as with all engineering choices sacrifices and balancing choices needed to be made. This street chose driver comfort and speed over human lives. It may have taken a long time for those small errors to accumulate and align for a death, but they were omnipresent.

A detterent for not following posted motor vehicle regulations.

Not following posted motor vehicle regulations is extremely common in Canada and America. 99% of the time, these failures lead to nothing.

You sped a little? Nothing happened.

Took that "yellow" light that was probably red? Nothing happened.

Changed lanes improperly? Nothing happened.

Exited your lane a little bit? Nothing happened.

Every driver commits many infractions that lead to absolutely nothing happening all the time. But that one time it costs lives, livelihoods, or property. The rules exist to protect against that one time. North American society has decided the we will not engineer away failures. We've decided we won't educate away failures. We've decided we will barely enforce failures. Because of this we have forced our hands into operator responsibility and civil liability, and that obliges steep reactions to driving failures that have consequential outcomes.

having no realistic alternative to driving

I am 100% certain there is a bus route along this road. On account of Diego Cardoso de Oliveira, Matilde Ramos Pinto, and their two children being killed waiting for one.

A bus stop that was built on sheer bolts (engineering decision)

A bus stop that was in the recovery zone of the roadway (engineering decision)

On the other side of a curb that allows vehicles to exit the roadway into that recovery zone instead of diverting them into the other lane on a lane departure (engineering decision)

On a road that a driver felt comfortable doing 70mph (112 kph) on when there arw sildwalks and bus stops (engineering decision).

In a vehicle that did not alert the driver of the danger of travelling 70mph (engineering/political decision)
