First: I have no reason to trust Russia's reporting on their COVID statistics. Nevertheless, Russia probably should enact more road safety measures had they the resources to enforce them because Russia's road fatality rate is among the worst of developed nations in the world.
All that aside: road accident deaths aren't contagious. They happen and they are done. There is no possibility of [exponential] community spread, I don't have to worry about infecting my grandmother, your grandmother via you, or the immuno-compromised children my wife cares for in the hospital.
