Interesting that when it was reported in our area the news feed on the radio included the final line stating "the president was not delayed by the accident..." as if that was the most important thing on everyone's mind. Obviously the pres didn't stop although supposedly the paramedics traveling with the convoy stopped to render aid per the report.
When I rode "for work" we did several escorts around the state for the Prez and other VIPs over the four years I was on the bike. The President and Vice President's motorcade would not even think of stopping if one of us went down. There was an ambulance in the procession, but it was for the package. We began to bring another ambulance for one of us if needed.
