LOL! You think that 44 m.p.h. is "too fast?" LOL!
Then he mentions one of the two turns that should NOT have been permitted in the first place! LOL! The motorcade could have, and should have, come straight down Elm Street to avoid the need for any turns. IF Main Street was needed then the motorcade could have stayed on it and connected to the Stemmons Freeway past the Triple Underpass.
Cool story bro, but as usual you are totally clueless about the evidence.
The Main/Elm/Commerce/35E intersection is specifically designed to discourage anyone on Main from trying to get onto the ramp to 35E. That's for safety: people aren't going to be turning from Main across Elm to get on 35. For the limo to go from Main to the ramp, the the limo would have to execute a u-turn onto Elm Eastbound, then immediately execute another u-turn to get onto the ramp. The limo would have to slow to a crawl to make that happen.....if it could execute the maneuver at all without resorting to 2- or 3-point turns. Long wheelbase vehicles aren't known for their cornering agility. If people would just look at a map, or an aerial photo they'd see why a Main-to-35E path doesn't work.
I've always wondered where the 44mph thing came from. I figure it started either with Garrison or Prouty, who claimed that it was some Secret Service requirement. The thing is, in 30 years, I've never seen anyone cough up any documentation whatsoever showing that it really was a requirement at the time (and, yes, I've asked).
