Mr. SPECTER. How fast was it possible to accelerate your automobile at that time? Mr. GREER. Well, it is a very heavy automobile, and it does not pick up too fast on account of the weight. I have never tested to see how many feet I could travel in a second. I have never had any reason to test it to see how much I could travel. But it was in low gear at that time, and that helps you to accelerate a lot faster. Mr. SPECTER. Would you characterize it as a very rapid or a rapid acceleration? Mr. GREER. No. Mr. SPECTER. Or how would you characterize it? Mr. GREER. It is a very smooth car taking off anyway, and I would say it wasn't rapid. It is fairly fast in low gear but not rapid like a light car will be. Mr. SPECTER. Does that car have an automatic transmission? Mr. GREER. Yes, sir. Mr. SPECTER. And what are the varieties of forward speeds in the vehicle? Mr. GREER. It has a low gear and then it has drive one and drive two. It has two top gears. One has, one probably has, free wheeling more than the other. The other is not a free wheeling gear. Mr. SPECTER. How fast can the car be driven in the low gear? Mr. GREER. I would say safely you can drive it up to 40 miles an hour in low gear. That is estimating it at 40. Mr. SPECTER. From the time of the first shot until the time of the third shot, was your car moving in a straight line or in an arc or how would you describe it? Mr. GREER. I was following the contour of the road, the center of the contour of the road as it goes. Mr. SPECTER. What is the path of the contour of the road? Mr. GREER. Well, at the time I didn't think much of it but it is a little, there is a little bend in the road going to the underpass. Mr. SPECTER. Did you hear anyone in the car say anything from the time of the first shot until the time of the third shot? Mr. GREER. Not to the best of my recollection, I don't remember. (At this point, Representative Boggs entered the hearing room.) (Discussion off the record.) Mr. SPECTER. Mr. Greer, did you hear anyone say anything from the time of the third shot until the time of arrival at Parkland Hospital? Mr. GREER. No, sir; I didn't. I didn't hear, I can't remember hearing anyone say anything at all. We were quite preoccupied to get to the hospital as fast as we can, as we could, and that was my mind was really occupied on what I was doing. I didn't hear anything. Mr. SPECTER. Do you know what speed you were traveling at en route to the hospital? Mr. GREER. No, sir; I couldn't say. I was just getting through the traffic and through the streets as fast as I could get through. Mr. SPECTER. Would you have any estimate at all on speed? Mr. GREER. I would estimate that I must have been doing 40 or 50, at least 50 miles an hour at times. We might have been going as fast as 50 miles an hour, I am sure. Mr. SPECTER. When you accelerated your automobile, did you at any time come alongside of or pass the police car in front of you?
