Indeed. "fetches le vash." :) Classic.
Try this as an evolutionary explanation. In terms of road accidents the essential element is the vehicle. A person running full pelt into a cow will not damage the cow severely. Cows mass significantly more than humans. They have hair which increases their visual silluette. Further, being quadrupeds they have a greater visual impact at a relevant level (say 1 meter).
Humans tend to mass significantly less than cows and dispite the advent of puffer jackets tend to wear figure hugging clothing when jogging. Being bipedal their silluette is broadly upright. This makes them more similar at a cursory examination to trees which humans have become adept at visually screening out as insignificant (compared to, say, cows or merrygorounds.)
The driver of a skoda octavia will usually occupy the central portion of either the left or the incorrect

side of the road. At an average speed of say 42 mph on a winding road their reaction time will be short.
If said vehicle comes across a human jogger the time it takes to process the information as an obsticle is smaller than with the cow for the visual reasons outlined above. This increases the chance of the car hitting the human compared to the cow.
Given the difference in mass a cow will cause more damage to a car in a collision than a human. Even one in a puffer jacket.
Assuming that the car succeeds in seeing the obsticle in time to swerve it has two options. If the jogger is a cow the car must swerve into the side of the road. In country lanes (where the incidence of cows is higher). The most likely outcome is that the car ends up in the ditch or wrapped around a tree. result, one less car. One unharmed cow. one car off the road
If the car comes upon a jogger it is more likly to be in an urban context. To acheive clearance The car must swerve into the opposite carrageway where there may well be an oncoming car. Result, two less cars, same number of joggers, cows unharmed.
In either case the cows come off better than the cars.
Conclusion
Cows are, by physical design and by learned behavior more suitable for jogging on roads than humans. Eventually if not stopped, this trend may lead to an uncontrolled number of cows on the road and the complete extinction of cars.
Disclaimer
This examination takes no account of the long term effect of the potential soft tissue injuries caused by the cows hard hoofs (increased shock) when jogging on an asphalt surface. Humans have the advantage of both fibrofatty padding and nike air trainers. This may attenuate the disturbing trend outlined above.
