Error: Cannot simulate track

[Max T Dickens]

I converted my own coords file to geojson, but it doesn't seem to work. Here's a part of my geojson:

{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "geometry": {
        "type": "LineString",
        "coordinates": [
          [
            12,
            34
          ],
          [
            56,
            78
          ],

So I tried again to draw the track directly on your map. And since I'm not driving a car on the road, I have to draw all the points myself. But after doing so and downloaded it, it didn't seem to be the track that I wanted, but instead the track that fit to the road.
