Alan,
It's impossible to tell what the time elapse would be.
Why?
If you use the Bell/Towner sync and plot it, their LOS intersect creates a wider turn radius than most believed to have occurred.
Truly described it and that was at least one reason for the Towner splice. imo
Another would probably be, as you have long suspected, the action upon the TSBD steps so clearly in view from Towner's position.
With that said and the splice time/wider radius being discounted, it would have been a distance of approx 25ft traveled at an 8.6mph average speed = 25/12.64ft persec = 2 seconds.
Mr. TRULY. That is right.
And the President's car following close behind came along at an average speed of 10 or 15 miles an hour. It wasn't that much, because they were getting ready to turn. And the driver of the Presidential car swung out too far to the right, and he came almost within an inch of running into this little abutment here, between Elm and the Parkway. And he slowed down perceptibly and pulled back to the left to get over into the middle lane of the parkway. Not being familiar with the street, he came too far out this way when he made his turn.
Mr. BELIN. He came too far to the north before he made his curve, and as he curved--as he made his left turn from Houston onto the street leading to the expressway, he almost hit this north curb?
Mr. TRULY. That is right. Just before he got to it, he had to almost stop, to pull over to the left.
If he had maintained his speed, he would probably have hit this little section here.
Mr. BELIN. All right.
