Obviously we still don't know the full story, and I do feel there is more to it, but from another article: ""While driving in the area of Barnes and Noble, Mr. Rein stated his right foot became stuck on the accelerator and his vehicle accelerated," State Trooper Andrew Chiachio wrote in a police report. "Mr. Rein stated he used his left foot to try to brake, but was unable to stop the vehicle and crashed through the front of the Apple store.""

The gas pedal on my car got stuck once (I later figured out why and it was really stupid and 100% not the cars fault), and I immediately reacted by braking, shifting into neutral (automatic transmission) and steering the car off the road. I was just accelerating at a green light, so it all happened under 10 mph, but it was scary.

I think we need to make people re-take periodic driving tests/courses to re-educate older drivers. And yes, 50s is older.
