I find it quite refreshing that somebody gives independant evidence for an assertion. Being one myself who never lets a good fact get in the way of an opinion, I am grateful that someone has taken the trouble to get some facts.
Your statistician is quoting 'facts' without linking his source.
That does not a fact make.
He has no idea how many near misses occur as a result of RLJs.
It is a daily occurence in London.
If the motorists taking avoiding action (and in so doing often swerving into the path of oncoming traffic thus endangering even more lives) didn't take that avoiding action, the stats would be even grimmer reading.
