I did this for transportation - to try and convince my wife that driving a car was not, in fact, safer than biking.  I don't remember the absolute numbers, but biking and walking were the lowest risk of death or serious injury per mile traveled for personal transportation, and nearly the same (the Williamsburg colonists were onto some with their walking helmets).

Driving a car is three times more dangerous than walking/biking per mile.
Riding a motorcycle is 5 times more dangerous than driving a car (which is maybe where her false intuition comes from).  In fact, motorcycles are equivalent risk to active duty in the Iraq war (as an American - we prefer to kill people from other nations to feed the MIC).

Buses and trains were 5 times safer than cars - i.e. safer than walking/biking.  I take my bike on both quite a bit for longer distances.

Airplane travel was the safest of all per mile (this would be 2005, when I sold my car and got a bicyle).  I wonder about it now that many pilots are dropping dead from the mandated Pfizer shots and airlines are considering relaxing copilot requirements.

I would suspect this is highly variable based ont he location.. Biking in the city is far more dangerous than through the woods or in the suburbs I suspect.

Moreover it would vary greatly from city to city. Cities with guarded bike lanes would probably be quite safe whereas cities that require cars to occupy the same space as bikes are likely very dangerous.

 This was US transportation stats - averaging city and country.  

The problem with country roads, is they are narrow and twisty with no shoulder or bike path/lane - and are actually quite dangerous when you encounter a car, even if there are fewer cars.  

Cities and suburbs have extensive bicycle infrastructure, with a network of "no motorized vehicles" paths and lanes.  Plus "secret" routes where no car could ever go that are fun to discover.

Not in philly, though we are probably well outside the avg. In philly there are few if any bike lanes. When they exist they arent guarded. And the drivers are more than happy to kill you for sport :)
