They are likely studying individuals that retired without getting fatally stabbed or shot on the job.

It's not violence from the job but their job was generally bad for their health in other ways. Sitting all day without getting up and driving around with windows down getting all this UV.

Also, older ones were exposed to a ton of cigarette smoke.

Also road accidents.

I could imagine taxi drivers have fewer fatal/grave road accidents than the average person or at most slightly more. They tend to drive in cities, are more trained, can't drink or do drugs on the job. For London only 1 taxi driver has died in a traffic accident since 2020.

If you drive more you are more likely to be in an accident, that's just how roads and accidents work.

Sure they might be better and per unit of time they drive they must have miniscule amount of accidents.

But if there's a 0.001% chance per hour driven, then over enough hours a few accidents are inevitable.

They don't just add more hours of driving they replace a small amount of risky hours for a lot of hours of low risk if they change location/job.

Also Drivers are generally less likely to die in accidents in urban areas, on high ways it's different.

Pedestrians are a lot more at risk. So that's unsurprising that annually 1/2 taxi driver might be fatally injured in one.

But I would assume the ratio of other drivers to taxi drivers would be high enough that this number should be zero as well.

I'm gonna go out on a limb and say that not even a double digit percentage of taxi drivers' careers are ended due to violent attacks. Taxi driver doesn't even appear in the U.S. Bureau of Labor Statistics top 20 most dangerous jobs.

> not even a double digit percentage

That's actually crazy if that's as low as you dare guess. I would have easily guessed it was like, a fraction of a percent. 1 in 10 would be fucking nuts.

That's like, almost all of them.
