Hey Dan,
I was messing around and this is almost getting what I need. It works until I add the third marker. So I’m kind of using the markers distance markers. Start=0 Half=100 and End=150. I can adjust the markers for each car. It just keeps giving me an error when I add that third marker.

thisComp.layer("Null 9").transform.position[0];

 m1 = marker.key("Start").time;
  m2 = marker.key("Half").time;
m3= marker.key("End").time;
  linear(time, m1, m2, m3, 0, 100, 150);

All anchor points are the same, I just copied the cars and adjusted the x-position. The nulls I set up in cinema are children to the car so they weren’t animated.

Here’s another example which I think explains it a little better. The bottom car should read around 83-85ft but is at 94ft. They are both around the same x-position when they are by the blue line. Does the speed of the car have something to do with the value increasing so fast?

x=thisComp.layer("Car 104").transform.position[0];
carStart = -30;
carStop = 3169.9199;
numStart = 0;
numStop = 104.00;
ease(x,carStart,carStop,numStart,numStop);

It is slightly ahead but it’s showing a 4ft difference which is way more than it should be. If there was a marker there for 55ft no mater how fast the car was traveling it would still hit that 55ft mark at that same point. Does it have something to do with the velocity of the car?

Klemens you are correct, the little things you always overlook. Thanks

[Justin Giudici]

That is exactly what I needed thanks for the help Dan!

Sorry for the vagueness Dan, I’ll try and explain it a little better. I have a car that is stopping and a stopping distance number. I want the number to increase at the same speed as the car, so when the car is slowing down the number count slows down as well. Pretty much using the speed of the car to control the counter speed.

Awesome, thanks Stephen. Still getting use to Motion so I hate when I run into differences like this hahah.
