Just a crack from the concrete shrinkage .. nothing to worry about
I often thought there should be a sensor on the Throttle handle to detect if a hand is on it to shut down if not....One time I was in a speed boat and the guy throttled it full throttle and it threw him backwards over the seat, another guy jumped into the driver seat to take control.
Alabama, as do many states, requires a "dead man switch" that they call "ECOS" or "Emergency Engine Cut-Off Switch". The boat operator connects the ECOS lanyard to their person or clothing and if they fall out of the boat or the seat it kills the throttle.
That likely would not have been of any benefit in the above case if an unconscious person is still in the seat. A more suitable and intelligent sensor would be in order, such as an eye monitor.

And people are losing their $#!+ over an eye monitor that is supposed to become mandatory in 2027 and newer vehicles.
True.
I recall circa 1998 several years before I retired an elderly man in a Ford Explorer had a medical episode in the city where I was the traffic signal super. He ran over one our small 10 ft. poles with a pedstrian signal atop it and then stopped up against a concrete retaining wall, unconscious and foot down on the throttle. I was nearby and got there before the police and there's was a huge pile of tire rubber behind the vehicle and the tire smoke cloud in the air looked like a house fire. No one else was injured, AFAIK.
Sometimes some fool runs a red light, then some other fool follows suit. Once in a while, there might be a third jackoff fool to follow the first two...
tell me this is a light malfunction....
tell me this is a light malfunction....
That's my guess, you see all the cars on his right waiting even though the light is green but the car in front of him went/made it.
@TonyR would know...wonder while he worked on lights how many times he saw this kinda thing...
I have to admit, I have followed behind an eight-wheeler/trailer to find I had ran a red light.
@sdkid , I doubt that it's a "light malfunction" for 2 reasons: first of all, a link below it where it exists on "X" purports to show the side street view and it looks red to me. Secondly, all traffic signals have an independent, outboard piece of equipment termed a "conflict monitor" to detect such malfunctions and place the signals into flashing mode, usually red flash for all directions.
These conflict monitors didn't exist in electromechanical systems and came about in the late 60's when solid state (dual SCR's or single triac per color) came along and often failed in the "on" state. As time went along the conflict monitors became more sophisticated and by the early 90's they also monitored more than one color incorrectly displayed per direction, NO color displayed per direction and even a too short of a clearance interval displayed between conflicting greens....such as only a 1 second yellow when 3.0 seconds is usually the mandated minimum yellow time. In reality the all-red is added to that so if you get less than 3 seconds from one green to a conflicting green, it can go into all-red flash. Fortunately, these newer conflict monitors have pretty good diagnostic displays to help the tech diagnose what failed so it can be addressed.
The conflict monitor also looks at critical voltages and monitors a "heart beat" (watchdog) from the microprocessor-based traffic signal controller in case it freezes. In many jurisdictions you can't unplug ithe conflict monitor without the signals going into flash. In CA (at least when I was there from ''74 to '04) you COULD unplug it to help troubleshoot BUT you could not close the cabinet door (as if you were leaving) without the signals going into all red flash.
