By many measures, advancements like seat belts and airbags have made vehicles dramatically safer for drivers and passengers.

But as our cars get bigger and bigger, what about the safety of those outside of our vehicles

Ali Rogan reports on how federal regulators are looking at a pedestrian safety now

and whether new rules can help curb the rising number of people killed on our streets each year in the

U.S.

So these are all, these are all from her last summer.

Jessica Hart is showing me photos of her daughter, Allison, or Ali Ali as her friends and family called her.

This is totally her running through the water just joyful in her own skin.

I love how so many of these pictures she's in motion. She's jumping and yeah.

She didn't need all the things to just have fun and run around and be happy.

In September of 2021, Ali's life was tragically cut short.

She was killed while riding her bike with her dad near their house in Washington, D.C.

Allie was just five years old.

They were going down the sidewalk and she went into the intersection of a four-way stop.

She was in the crosswalk in a school zone.

And the driver of a van didn't make a full stop and see her and hit her.

And we think she died on impact.

City law enforcement officials didn't file any criminal charges against the van's driver who remained at the

scene.

Allie was one of more than 8,000 pedestrians and cyclists killed that year.

It breaks my heart every day.

So her last moments were moments of terror.
