There is an important factor in the equation that you've left out:
"Drive safely".
Even the safest car on earth won't save the occupants if they drive
irresponsibly.
There was a time when Volvo drivers could pretty much be expected to be
the most courteous and safe drivers on the road.
In the 240 days, I would have said that the possibility of a Volvo
crashing into a Volvo was zero. Nada. Zip. Just wouldn't happen because
Volvo drivers simply don't put themselves into situations where that
would happen.
Nowadays ?
