I really can't find the ways.

I did my testing site https://ideal-works.com/ngeeannopenhouse/

function positionCar()
{
  var  scrollY = window.scrollY || window.pageYOffset;
  var  maxScrollY = document.documentElement.scrollHeight - window.innerHeight;
  var  path = document.getElementById("path1");
  // Calculate distance along the path the car should be for the current scroll amount
  var  pathLen = path.getTotalLength();
  var  dist = pathLen * scrollY / maxScrollY;
  var  pos = path.getPointAtLength(dist);
 
  // Position the car at "pos" totated by "angle"
  var  car = document.getElementById("car");
  car.setAttribute("transform", "translate(" + pos.x + "," + pos.y + ")");
}


// Reposition car whenever there is a scroll event
window.addEventListener("scroll", positionCar);

// Position the car initially
positionCar();
<svg id="svgPath" width="100%" height="100%" x="0px" y="0px" style="overflow: visible;">
