- Legally, you are correct, but as I already stated, good drivers both do not cause and avoid being in accidents. This is why insurance rates may go up if you are repeatedly in accidents (even if not legally ever at fault).
Driving below traffic speed is dangerous and will lead to rear end collisions, among other things.
Just the fact that these cars have been in 11 rear end collisions in the limited number of miles they have driven is a huge red flag. That's not a statistical anomaly, that is unsafe driving.
The "well, if everyone else drove slower, safer, less aggressive, etc." line of reasoning is reasonable logic for discussing something like public policy (e.g. enforcing speed limits, reducing speed limits, etc.)
but horrible justification for driving unsafe in an environment where it is known that everyone else will behave in an non-ideal manner.
It doesn't matter if the driving style would be safe in a different environment where everyone else drove the same way because reality is reality. You must drive safe for your given reality.
This is why many humans drive differently in a city than in a rural country. It is safer to drive socially conscious, recognizing the reality of the typical driving behavior of those in the vehicles around you, rather than drive in a rigid, dogmatic manner that is statistically less safe -given the greater number of accidents that will result.
